Made the trip. Rode the mass ride, so-so, could have done way better, but I'm still happy with it, because last year my place was 1140.
My place in 2011 - 416 out of 2790
Time 1:05:18, gap to the leader +0:12:03, average speed 33.5.
Reasons in order of importance
1. Didn't buy a battery for the bike comp, the old one died, and I rode without a comp. Didn't know how fast I was going or if the end was near, and ended up saving too much energy.
2. The tires were wide and knobby, didn't take the rear rack off (see the point below).
3. The day before, we rode 80 km from Ogre to Sigulda, in the rain. It was a boring ride to be honest, on asphalt, the only thing that brightened up the outing was the swampy forest at the start.
4. Spent the night in a tent.
5. My socks were wet, and I dropped my water bottle close to the start of the race.
For next year, the bare minimum goal is to make the top hundred.
Tracks under the cut, if anyone's interested.
