Mike couldn't pass up clear skies and high pressure, so it looks like he's rolling early. I've got the first few points already - shown in the above map.
The Iditarod Trail Invitational went off at 2pm AK time, and it appears Mike waited for the dust to settle, then rolled off, likely with little fanfare. His last point at Knik was at 2:16pm.
2 hours later he's covered at least 10 miles, following many a foot, tire and ski track, no doubt. It'll be interesting to see how late into the night he rides, and how many racers he manages to pass (!) while doing so.
I'm looking forward to the first reports from the race.
