Trails? Fah.

Who needs 'em?

Of late, not us.

It seems those whom would have every local trail filled with riders from near and far every waking moment of every day may soon get their wish.

What they don't seem to realize that they are also signing up for is congestion, bad feelings from said congestion, altercations (necessary or not) brought on by Stravassholes doing what they do, trail widening and braiding, sanitization and re-sanitization, and other sundry results from cramming too many people out there at any given moment.

What will it take to get them to understand the big picture, the error of their ways?

Clearly we have no idea, because they haven't listened to us.

Last week Greg and I both hit the eject button and left the trails entirely.  Lots of washes to be ridden,  none of them currently occupied.

Silence was noted and appreciated by all, er, both of us.

Aesthetically pleasing slabs and layers were present, um, everywhere.

We carried boats with us on one of these microadventures, but ended up not needing them.  Small failure there -- next time we'll go one or two washes further up and hopefully end at moving water.

The beauty of any off-piste adventure is the simple fact that you don't know exactly how things will turn out.  Is the wash even rideable?  Do pourovers exist?  Can they be hiked around, can bikes be passed down, or will we be forced to retreat?

All good questions.  The answers can't be googled, and they sure aren't on Strava.

Perhaps someday the idea that a trail has value even it isn't flooded with humanity will catch on.

Locally, that idea seems doubtful but not impossible.

Until such an eventuality comes to pass, you can have 'em -- we'll be in the washes.

Lost Coast North in moving pixels.

I gave a blow-by-blow account, complete with heaps of pics and a generous amount of beta, from this trip back in September.

I had hoped to finish and release the accompanying video at the same time, but life got in the way of that objective, as it often does and should.

One very small reason for the delay was uncertainty with which direction to take production of the video.  I had almost two hours of footage to distill down, which could have gone many different directions.

Many times in the past I've spent way, way, way too much time drilling down through the video, being hyper-vigilant about every detail along the way, to arrive at a polished end product that I was proud to share and happy to re-watch myself.  Not possible to overstate the amount of time that it takes to do that, and the amount of additional time it takes to do it well.

One major consideration along the way: target audience.  Sometimes it's just the people that were on the trip.  Sometimes it's for a wider range -- like people that might consider repeating the trip.  Other times it's for everyone: friends, family, small flightless birds.  In distilling the clips down you've got that target audience in mind the whole time.  Regrettably, you're also faced with the daunting reality that if your video encroaches on or exceeds ~4 minutes, probably no one is going to watch the whole thing.

Far too often I've busted ass to deliver a sub-4 minute video.  In that process so much is lost -- so much of the story, the context behind it, the meat from the bones of what was done and seen and experienced.

I've also noted, when watching videos made by friends or peers of similar trips, that if the video ends at ~4 minutes I always want more, and the longer these accounts run the more I understand of the place, the route, the challenges.  I always want to see more.

Thus, this time around I've simply said "no" to the endless and thankless process of getting under 4 minutes.  I *did* winnow the footage down from 2 hours to 20 minutes.  I included a handful of voice clips not because they're apropos of anything much in the vid, just because they help to share the mood and tone that accompanied our travels.

One detail that doesn't come through in the vid: How much it rained.  I think this is because I simply didn't bring the cameras out unless it was only drizzling or less.  Man did it rain.

Without further ado...

Grand Quickie.

A few weeks ago I attended the annual Grand Canyon self-support with 8 other likeminded folks.

It'll be weeks until I have a chance to sit down and process photos, and probably longer until I've fully processed the whole trip.

But I wanted to share a teeny, tiny slice of awesome before winter bleeds into spring and my schedule goes apeshit.

First clip is from Tiger Wash.  We all know that the seam monsters can wreak havoc -- and that they often do.  This was the only time on this trip that I got absorbed/swallowed by one.  I had to wait a few seconds until it released me to the surface to roll up.  Getting knocked over by exploding waves is expected.  Getting swallowed by a seam was unnerving.

Next clip is Hance.  This was kind of our wake up call that the big stuff was beginning.  I had wide eyes during this one, and the rest of the group had wide eyes after it!  

Next is following Thor into Lower Tuna.  What leaps out about this clip is that Thor is no longer Timid Thor that I met a few years ago on the Selway and Lochsa. A week at the NZ kayaking school and a year of Colorado creeking have morphed him into a Meat Seeking Missile.  I didn't often have interest in following his lines on the Grand.  This was one where I was glad I did.

Next clip is Lava.  All I can say is that not scouting adds a certain flavor to the in-run, and I highly recommend it.  The run is over so fast (in the POV) that it's hard to imagine what all of the nerves leading up to it accomplish.

And, finally, we have self-immolation practice at 209.  When the trip is rapidly coming to a close and you only have one more chance to plug a hole, you take advantage, right?

Just thought I'd share some stoke on a Friday evening.  The season approacheth!

Jeny and The Race: The mental mind.

The ITI starts in 2 days!

There is little that can be done to increase fitness at this point.  Jeny can rest and show up recovered and ready to go, or she can not, but she can't get any stronger.  

I dropped Jeny at the airport at dark-thirty this morning, and she'll transit through several other airports before arriving in Anchorage this evening.  If you're anything like a normal human being, you spend lots of time "devicing" while killing time in airports.  In that way Jeny is normal.  She'll read a little news, maybe catch up with friends and family, possibly get some actual work done.  

Undoubtedly she'll also check a few weather websites to see how things are shaping up along the route.  My experience is that the more you look at those seemingly innocuous forecasts, the more you're sewing the seeds of uncertainty in your own preparation.

Weather forecasts being what they are, you come away from each one less sure about what they're telling you.  60% chance of sun is virtually the same as a 40% chance of snow, but the way that you prepare for and react to each is emphatically not the same.  The more you think about the likelihood of snow, the more you wonder how prepared you really are for it.  


-If the snow is light and dry, and it comes in on a wind, then the trail will drift in and traction is very difficult to find.  Bigger knobs on your tires are quite beneficial to the end of riding vs. spinning your rear wheel and digging holes, or being able to control the front end of the bike.  Even though we've tested, discussed, tested, and retested tires, and made the decision to run Bud/Bud based on past conditions and current forecasts, Jeny wouldn't be human if she looked at these forecasts and didn't wonder if that was the right choice.

-If the snow is wet and heavy it becomes easier to ride, but it has the ancillary effect of weighing down the ice on the frozen waterways that constitute the bulk of this route.  Pushing down the ice pushes water out on top, creating overflow.  Ever pedaled or walked through standing water at -20*?  It happens, and if you're unprepared for it you're going to have a bad day.

Where am I going with all this?

If at this stage you have any cause for uncertainty with any of your preparation, the littlest things will cause you to second guess the steps you've taken to get here.  Second guess enough steps and suddenly the most prepared person is debating whether to start at all, or considering adding a dozen pounds ("We pack our insecurities") of ultra-lightweight gear to their kit.  This isn't specific to any one demographic or individual, although it does tend to hit us CDO folks harder.

The solution?  

Simple: Remind yourself where you've been en route to this moment.

When Jeny first made the decision to head north back in early January, I sat her down and shone a very bright light in her eyes, then explained to her that she could start the event the very next day and do really well.  A lifetime spent outside in similar conditions has familiarized her with what she'll experience up there.  She nodded in agreement but I could tell that she was skeptical.  Then I explained that since she had 6 weeks left to prepare, we'd leave no stone unturned doing just that.  And we have -- well, *she* has.  Jeny buckled down, focused and really put in the necessary effort to dial in her fitness and gear.  When I reiterated that to her yesterday she again nodded in agreement, but again I could tell that she was skeptical.  And I get that -- there are just so many variables involved that you can't help but to wonder which of them you could or should have spent more time with. 

To that end, all Jeny needs to do is go back to the beginning of this series of posts and re-read each one to realize that she has, indeed, prepared in a way that will deliver her to Knik Lake on Sunday morning as prepared as any ITI rookie will likely ever be.  She has scrutinized every piece of clothing she'll wear and done research to understand what sort of options she has.  Then she's gone out and ridden (and pushed, and camped) in each piece, overandoverandover, for the past ~6 weeks.  After each ride she's made some minute adjustment (cutting, sewing, amending) to each piece of gear -- usually to make it fit better or to become more invisible when worn -- and then she's gone out and ridden some more.  Again, and again, and again.

Apply that process not just to your clothing, but also to your bike, your food, and your safety kit, and what do you get?  Eventually you get a sense of confidence at having left no detail unexamined.  Or at least you should.  Once you've been out on the actual trail and seen how well things work, then that confidence can begin to sink in.

But Jeny's not there yet: She's got a long 2 days before she pedals away from Knik and can begin to understand this for herself.  In that time she'll meet lots of new people -- mostly fellow racers -- and she'll have a multitude of conversations about the race, the route, the weather, and always more talk about gear.  It is cyclical and seemingly interminable.  As with the weather forecasts, each of these conversations leaves you with a sense of uncertainty about the prep you've done to date.  Invariably someone will ask how you plan to deal with X scenario and, even though you've thought it through, experimented, and have a solid answer, *their* answer might be different from yours, and this'll give you pause.

There are very few black and white answers to the scenarios they'll face out there.  The one certainty is that if you have confidence in the solution you've devised -- whatever it is -- then that's good enough.  Never having been out there makes it difficult for some to grasp this simple truth.

Last point about the mental aspect of traversing the Iditarod Trail: Things never go exactly to plan.  You're pushing hard in an unforgiving and potentially hostile environment for too long to do everything 100% perfect.  Mistakes happen to everyone, sometimes in rapid succession.  Dwelling on them -- beating yourself up -- does little to teach and less to get you further up the trail.  The person that can make a mistake, digest and embrace the lesson, then drop it trailside and move on is the person that emerges victorious from the ITI.  And from life...

Jeny is a gifted athlete with a lifetime of outdoor experience, and because of this she sets very high expectations for herself.  Failing to live up to them -- whatever that means to her -- can send her down a mental spiral that's difficult to pull out of.  To the end of combatting that she's devised a handful of strategies to keep herself on track.  Slowing down, stopping for a break, grabbing a midday catnap, preparing and then eating a hot meal -- all of these serve to keep her from getting too far ahead of herself.  Staying in the moment is The Most Important Thing.  Those are popular words these days, and might not get through to everyone.

So I'll put them differently.  Thinking too far ahead can be crippling.  Thinking of each task to be completed as sequential, and not cumulative, might be the best single piece of advice I can offer this late in the game.

The 2017 ITI starts this Sunday at 2PM Alaska time.  You can follow it here.

Jeny and The Race: Random minutia.

I've gotten a good chunk of personal emails about this thread from various friends and customers.  Some of them had questions that weren't worthy of a whole post, but that did deserve to be answered. There have also been a few good questions buried in the comments, and in various online spaces.  I'd like to highlight a few of those as well.

* * * * *

What are your preferred studs to use in the Vee Snowshoe?

For this event I don't think it matters too much. No sane person is riding the limits of their studs in this environment and that far "out there". They're more to keep a person upright in the event that they encounter some ice they weren't expecting, than to allow you to ride every off-camber glaciered stretch of trail along the way. Stock Vee, Nokian, Schwalbe, or 45N are all pretty much the same in that respect.

If we were talking commuting on black ice all winter long in some high-latitude city, my answer would be different.

How many pairs of socks do you bring?  How do you dry them?

Part of our routine for keeping trench foot at bay -- since our feet may not feel wet but with any sort of VBL system there is at least some moisture present all the time -- is to replace the moist socks with dry ones when we get into our sleeping bags at night. Thus we have a total of 2 identical pairs of socks on our persons the entire trip: One on our feet, and one in reserve. At bedtime the dry pair goes on and our feet get to dry out as we sleep. The felt liners do double duty as our sleep booties as well, saving the bulk, weight, and hassle of carrying something else to do the job. The wet socks that come off as we get into the bag get placed under our layers, against our bellies, the heat from which quickly and effectively dries them out.  

Come morning you already have dry socks on inside your liners, so as you swing a leg out of your bag to get dressed all you have to do is slip that foot into the shell of the boot. No way for cold or even discomfort to intervene, no thermal mass to have to pre-warm. Quick and easy.

Curious what you are using for your "go to" tubeless fat set up?

I've liked and believed in tubeless for bicycles for almost 2 decades now. It follows that I had to do lots of experimenting with stacking layers of tape to make things work tubeless way back when, and again ~6 years ago when I started fiddling with tubeless fat, because there were no readily available rim or tire options.

That process can be both intensely rewarding and frustrating -- as you are undoubtedly well aware -- and often both within minutes of each other. Fiddling with layering tape and struggling to understand why some setups worked and some didn't was very educational and I'm glad to have done it.

But every tape setup has eventually failed. Some lasted ~1000 miles. Most lasted far, far less. They rarely fail in the warmth of the shop/basement/garage, which adds to the frustration of the failure. So you stick in a tube, then try to scrape the schmutz off your hands before putting your gloves back on to keep riding. During a day ride? Not the worst thing. Many days out from home? Frustrating, unnecessary, and potentially unsafe.

There are a few fatbike rims these days that are turn-key tubeless ready. I build with all of them several times a week. Of these, the Bontrager Jackalope's are my favorites. Jeny will be using them on this trip. They require one lap of normal mtb width (~22mm) tape to seal the spoke holes. That's it. Once that lap of tape is installed, you can inflate and seat the tires using the teeniest, weeniest mini pump out there. No compressor. No floor pump. No hopping on one foot while holding breath and hoping. No drama at all. Jeny proved this to both of us yesterday as part of her 'mechanical prep'. I wanted her to have confidence that if she flats she can fix it -- whether that means plugging it from the outside, patching it from the inside (which would then require her to re-seat the bead), or simply sticking in a tube.

So, in short, my answer is to stop fiddling with the layers of tape and use a real tubeless ready rim.

Would be curious as to the dropper posts you've found that work in the cold (anything below freezing). Too many of them stop functioning at a hint of a cool breeze.

Jeny will be using the Giant Contact SL.  We love the RS Reverb in summer months, but as you've described it doesn't work well in cool much less cold conditions.  We've had the Giant down to 0*f without noticing any change in performance.  I suspect it'll be good for her down to -20*f or so -- which is colder than is forecast for the entirety of this year's ITI right now.  In the event that it fails, she has a small aluminum collar that she can lock onto it that effectively makes it into a rigid post.

I have Raynaud's, and I use Wolfgars even in the lower 48. Perspiration is an issue for me even in a full day ride, leading to chilled toes. I'm trying to understand why your solution helps with sweat management because it seems like it would be trapped inside those plastic bags. Can you explain?

Your toes are getting chilled now because your sweat is degrading the insulation through the day. Wet insulation isn't as effective as dry.

The plastic layer prevents your insulation from getting wet, meaning it is just as warm at the end of the day as it was at the start.

That aside, there is a growing body of evidence out there that says that a VBL system (which I have emulated here with the plastic) "tricks" your feet into producing less sweat, as they eventually sense that there is already lots of moisture down there, so hey, why not tone it down?

It's not proven scientific fact for every person in every scenario. More like lots of anecdotal evidence to support it.

Did you guys consider a 27.5 fat setup at all, specifically the Gnarwhal? I'm guessing it would be fast for certain conditions, but not wide enough for variable conditions? I wonder if it would be a good replacement for a studded D5 setup? Should be similar width but roll faster?

We did test a B Fat Gnarwhal setup for 5 or 6 rides. Alas Jeny's frame was built with 26 x 4.8's in mind, before B Fat existed, and the B Fat's edge knobs sit a bit taller (closer to the BB) than any 26 x 4.8" tire. Clearance was tight to the chainstays when the tires hadn't yet stretched, and we knew they were going to stretch so we removed them from the running.

Jeny wasn't sure she could tell any difference in float or traction from Bud/Lou to the Gnarwhals. She was running them unstudded.

I'm guessing the sleeping bags are waterproofed? Or is the conifer cover generally enough?

Most modern/good bags have a DWR that's good enough. Also keep in mind that good winter bags have enough loft that if snow falls on them, there isn't enough of your body heat coming through to melt the snow. It just sits there at ambient until you roll over, and then it falls off. If you have a Ridgerest (or other pad with little nooks and crannies for snow to settle into), the snow can slip off your bag and into these nooks. If you roll over on top of that snow, then you'll wake to find little puddles in those nooks as your body heat is able to melt the snow that finds it's way between you and your pad.  

The conifers are big in many places -- such that you can burrow in and be untouched except by wind driven snow.

What are your thoughts on pedals? Given that there could be deep snow conditions that require extensive walking/pushing, platforms may be preferred.

Pedals are like religion to people in winter races: Suggest that they're doing it wrong and you'll find yourself in the midst of a holy war.

Jeny and I both prefer to ride clipless in winter. Our local trails are soft or softer, and being clipped in gives you better control of the bike in marginal conditions.  

It is easier and less expensive to arrive at a warm boot setup when using flats. The tradeoff being that you lose some of that fine control when things get really technical.

No right answer, no wrong answer, just compromises to choose between.

I have, in ITI's past, taken a long-handled hex wrench so that I could remove my pedals for long stretches of pushing. In 2010 my pedals were off of the bike for almost 2 days -- from just past Puntilla Lake to roughly the Dalzell Gorge. Never even thought about riding in that section, so deep and unconsolidated was the snow, and it was nice to not intermittently thwack my shins on the pedals.

For summer fatbike/beach/packraft trips I think flats make more sense for lots of reasons. And for some of those I've used QR pedals like these.

Some great questions above.  Don't hesitate if you have others.

Jeny and The Race: Camp notes.

Newbies to the ITI might be surprised to learn that it is possible to complete the entire Knik to McGrath route without sleeping outside.  There are private homes, BLM cabins, and commercial lodges spaced intermittently along the route, such that if your pace is good and your luck holds, you'd never need to deploy your bivy gear at all.

Think about that for a moment and you might start to wonder why you'd carry the extra ~7+ pounds of gear if you didn't have to.

In a word, safety is why you carry it.  There is never any guarantee that the conditions will be good enough to get from one lodge to the next cabin, or the next, in any reasonable amount of time.  The trail isn't groomed and weather is unpredictable: Plan to sleep in a lodge, carry no bivy gear, then a ground blizzard blows the trail in or a snowstorm buries it, and your pace and plans just went out the window.  What then?  Cuddle up in spruce boughs?  It has happened and it will continue to happen to those that are willing to gamble with their personal safety.  Hopefully the end result will be nothing more than entertaining stories shared by those who've been humbled.  I have a few of my own -- for another time...

Out of respect for the place and desire for their own safety, most people carry a puffy jacket to wear when they stop moving, and a sleeping bag and pad so that they can get some meaningful rest.  How big of a jacket, pad and bag are up to you to determine, based on how long you think you'll need to sleep, what the temps are, and what kind of sleeper you are.  Volumes have been written (and will continue to be regurgitated) on the subject of sleeping comfort -- handily distilled down to inflatable pad vs. closed cell foam pad, and down vs. synthetic insulation in your jacket and bag.  If you arrive at the ITI start you should be able to intelligently discuss at least some of these theories and explain why you went the route you did.  Most importantly, you should have at least a few nights of experience camping in the gear you plan to take.  

Jeny has been busy this month, and especially on the weekends, getting out and riding alpine snow all day on Saturday, camping that night with the gear she's carrying, then waking Sunday, cooking a meal and melting snow to refill her bottles, then closing the loop back to the start.  She understands that there is no better way to learn than to make mistakes, and the more mistakes she makes now, the fewer she'll make in the ITI when the stakes are higher.

The lodges and cabins along the way are spartan in luxury but often seem heaven-sent despite that, largely because when your life is distilled down to what can be dragged in a sled or fit onto a bike rack, the simplest things like food and heat are most appreciated.  Stumble exhausted out of a -30* night into a warm building and that alone is enough: anything beyond that -- like a $5 can of Coke or a $20 cheeseburger -- is just gravy.  Because of this allure, and because there are ~70 people participating in the ITI, the lodges are *busy*.  Think a little more about this and you'll realize that it is very difficult to get meaningful rest inside any of these buildings because people are constantly coming and going, packing and repacking, excitedly talking to friends when they arrive, rummaging through food and trash bags, burping, farting, clomping around in boots, and just generally doing anything other than being quiet.  The person that can sleep regardless of external stimuli will do well here.  If you need anything resembling uninterrupted quiet to sleep, you should plan to sleep out.

Jeny is planning to sleep out.

Just because you ditch the chaos of indoors does not guarantee that all is well.  There are a handful of things that you need to do, and to understand, in order to ensure solid rest.

First, the event is only a ~week long.  Getting 8 hours of sleep a night isn't needed.  I *like* seeing some of these landscapes (both inside and outside of my head) through the filter of darkness tinted with a teeny bit of sleep deprivation.  The experiences are much richer, the stories more compelling.

Maybe that's just me?  Quantity aside, when I do settle in I want the sleep to be short but of quality.  I shoot for at least an hour, and never (intentionally) more than 4.  90 minutes seems to be the magic number for me -- less than that and I'm still groggy and grumpy.  More than that and, after the initial moment or two of rumminess wears off, I feel rejuvenated and ready to move.

It goes without saying that if you're only going to sleep for 90 minutes, you don't want to waste another 90 setting up and breaking down camp.  You want to be fast, efficient -- not just so that you can maintain your forward mojo, but also because breaking camp in the cold is *cold*: You haven't been moving to generate any heat, and until you pack up and move you aren't going to.  Learn to be quick by thinking proactively about how and where to pack your gear.  If you have to think about where something is your toes just went numb.  If you unzip a zipper or peel back some velcro and find that what you sought is indeed somewhere else, your fingers are now numb too.  You'll be surprised at the speed with which your extremities begin to chill straight out of the bag in the morning.  

Over the last ~month Jeny has refined her camp setup routine to where she needs only to remove the bag from her rear rack and she has her entire "camp" within: Bag, pad, puffy, cookpot, food, and stove.  Fuel is kept separate for many reasons, but is handy in a bottle cage on the bike so that once she's setup and in her bag, she can reach from the comfort of her bag to grab that bottle and start melting snow.

But I'm getting a bit ahead of myself.

First, you need to pick a good spot, and "good" is both different and relative every time out.  My goal is always to find shelter first and foremost.  We don't carry a tent, mid, or tarp on the ITI because the weight, bulk, and time spent setting up and tearing down aren't offset by the meager protection they offer.  It's no warmer inside of a tent than out, but it can be quite a bit wetter due to condensation from exhalations.  I'll never use a bivy sack in winter again after experimenting and learning how much moisture they trap next to and inside of your sleeping bag, thusly degrading the insulation.

We sleep out.  And that means we need to be protected from wind and falling snow.  Trees offer good shelter, although if you set up camp in a grove of cottonwoods and it snows overnight you might wonder about the truth of that statement.  When I say trees I mean conifers, where the needles can catch any snow that might otherwise land on (and melt on) you.  

So the very first step is to find a spot that's quiet, and that means getting off of and away from the trail.  Stomp a path out into the trees, far enough so that other nocturnal travelers don't even notice you're there.  Jeny had an anxious moment a few weeks ago when a midnight trail groomer saw her camp and came to check on her -- but never got out of his snowcat to do it.  There was never any danger but as the cat approached her location it was hard to convince herself that she wasn't about to be tilled into corduroy.  Once the driver saw that she was safely ensconced in her bag he flipped it and left her to sleep.  His intentions were admirable but her adrenaline hit couldn't subside quickly enough.  She'd never have woken had she been better hidden.

The trick to sleeping under conifers, as any To Build a Fire fan will tell you, is to remove any snow that might fall on you before you set anything up.  How?  Put on your jacket, pull the hood over your head, close all zippers, bow your head, and then kick the snot out of the trunk until the last bombs have whumped to the ground around you.  Good?  Good.

Next. stomp a trench out next to a big tree.  Why big?  Bigger circumference of protection, plus (hopefully) a healthy trunk to lean against while melting snow.  The trench is necessary because the snow is deep and soft -- stomping it out packs it into a ~level surface to sleep on.  Make the trench big enough that you can't inadvertently touch the edges and knock loose snow down onto yourself.  There is an art to finding the right size: I'm not here to tell you how to do that, I'm here to encourage you to go out and find out!  An added bonus is that the stomping warms you a bit before you shut down the turbines for the night.

Above is Jeny's campsite from last Wednesday, after she'd placed her bike and stomped the trench but before she'd laid out her bag and pad to start cooking.

Our camptime habits include walking the last ~1/4 mile to "cool down" and cook any residual moisture out of our layers, eating a few hundred calories while walking so that the fire is stoked before we get into our bags, changing into dry socks as soon as we get into the bag, and rehydrating a hot meal to give our bellies fuel for both recovery and heat production through the night.  If we're tired enough we'll often pass out before brushing teeth, but the feeling of fur on teeth is usually the second task I take care of when I wake.  The first being the need to pee, which is almost always what wakes me and signifies that it's time to move again.

Clearly there is nothing exhaustive about what I've shared here.  I intend it as a springboard to get people to think about camping not in the abstract -- but to go out and do it and learn to be good at it.

No time like the present.

Jeny and the Race: Tired.

Quality fat tire options are incredible these days, to the point where analysis paralysis could be a legitimate concern for your average ITI participant.

Even removing all of the tires smaller than ~4" from the equation still leaves one with a healthy pile of rubber to choose from.

Having been on the ITI route through a wide variety of conditions gives me some depth of experience to draw from when considering options.  I know that unless someone is holding a gun to my head I'd never willingly choose a smaller tire when a bigger one is available.  I also know that the decrease in rolling resistance from running tubeless is substantial, and again I'd never choose to start with tubes if the choice was mine to make.

Bigger.  And reliable tubeless.  That's a good start, but there's so much more: Tread pattern, thread count, rubber composition, and the ability to (easily and reliably) run studs all have to be factored in, too.

Because we have a backyard mountain that's received over 300" of snow already this season, and because that snow is deep, cold, dry, and with limited traffic to pack things down, it is not a stretch to say that we have an ideal place to test tires.  And we've been doing just that -- literally for years.

The snow is so deep up there that we can't get down to bare ice to test, but we have ice in the valleys and we can test ice performance down here.

The one thing our testing grounds rarely produce is real, strong cold: The kind you can expect in the Alaskan Interior in a "normal" winter.  That last bit -- the "normal" part -- is the elephant in the room, because winters just aren't what they used to be in Alaska.  -30's during the ITI used to be a given, with -40's common and, if you were truly blessed, you'd be gifted some precious time out at -50 and into the -60's.

In recent years the deep snow that was a constant companion on the ITI from the late '90's onward has twice been replaced by a veritable sidewalk of ice: Not hardpack, but ice so firm that studded tires were absolutely mandatory.  Conditions like that are the rare instance when bigger isn't better for tires.

Because the ITI is still several weeks away there's no way to say what the weather is going to be.  Thus the challenge becomes to test as many tires as possible in the conditions you think you might get, and to know which tires do well in which conditions, so that in the days leading up the event you can nerd-out on weather across the state, make some educated guesses, then install the tires that make the most sense.

With all of that as preamble, Jeny and I have already narrowed her tire choices down to three.  Pictured left to right are the 45NRTH Dillinger 5, Vee Snowshoe XL PSC, and Surly Bud.

There are lots of other tires that are similar in size to the range represented here.  Schwalbe Jumbo Jim, Maxxis FBF, FBR, and Colossus, Surly Knard, Surly Lou, Vee 2XL, and Bontrager Barbegazi to name a few.  These are all quality tires without question, but each had some characteristic that rendered it undesirable for Jeny for the ITI.  We're not going to go into detail on those -- instead we're going to focus on the finalists.

Of these final 3, the Dillinger 5 is probably the most popular tire among ITI participants over the last few years.  I attribute this to the oddball weather that has twice produced the icy sidewalk stretching from Knik to McGrath (and beyond), and for which the studded version of the D5 was a great tire.  I'll take it a step further and posit that had the "ice years" never happened, the D5 would never have found favor at the ITI.  And that's quite simply because in unstudded form it's a mediocre tire at best, and significantly undersized relative to the 2 other finalists pictured above.  45N labels it a 4.8" tire but it comes nowhere close to that size even on a 100mm rim.

If the conditions morph over the next few weeks to where the route is ice, ice, and more ice, and a small-volume studded tire seems to be called for, the D5 will be it.

That leaves 2: Vee Snowshoe XL and Surly Bud.  Worth mentioning that both of these tires use 120tpi casings and measure very close to 4.8" wide.

Pictured in the middle above is a visually distinct tire made by Vee, called the Snowshoe XL.  Vee calls the creme-colored compound "Pure Silica".  Once you remove the marketing geekspeak what that means is that the rubber has a slightly softer durometer that is less affected by cold temps.  This is worth mentioning because anyone that's tried any black-compound Vee fat tire on snow, and particularly in cold temps, has thought to themselves "Jesus, did someone throw out an anchor?! as they looked around and tried to determine why they were working so hard to go so slow.  Vee's normal black Silica tires are known to be very slow rolling, and that only gets worse as the temps drop.

The creme colored PSC compound rolls well in the cold, and this particular tire has a true 4.8" casing, on par size-wise with the Surly Bud tire sitting at right in the pic above.  If course conditions look to have a mix of soft snow, hardpack, and any significant quantity (defined as more than ~30 miles, total) of hard ice, Jeny will ride these Vee tires fully studded en route to McGrath.

So that leaves Surly's venerable Bud tire, which is hands-down Jeny's all time favorite fat tire.  I've ridden it to Nome and many, many others have ridden it to McGrath.  It is a known quantity, and while it is definitely not the fastest rolling tire, nor the best for rear-specific digging, it is the best overall "one tire" compromise that we've found to date.  It is a true 4.8" thus it has huge air volume for running at super low pressures when the snow is soft.  But it also has big, blocky, siped and directional knobs that give steering control and confidence in every snow condition imaginable.  Bud is unlike almost every other tire in that it works well in such a wide range of conditions, and yet somehow doesn't feel too slow when the trail is firm and the going is easy.

If Bud has a drawback it is that once you've gotten used to the confidence he gives, it's hard to seriously consider any other tire.  If the ITI shapes up with "normal" snow conditions this year, which means little to no ice, Jeny will leave Knik Lake running Bud front and rear.

Without question there will be many that disagree with the direction our testing, thinking, and conclusions have gone.  And some of them will have valid points for their disagreement.  We're open to hearing these opinions, provided they are backed up with detail on how you arrived at them.  In short, provide enough background so that we might all discuss and learn.

Thanks for checking in.
