Lap 1 was a little slow, but there were some major traffic jams in the singletrack and trees. The double track is smooth and fast with a couple turns to keep you on your toes.
No real problems for me on my lap other than the slowness. The next few laps will be crucial though. I rode all the sections I wanted to, but had a little trouble keeping my heart rate down. I rode some sections I had planned to walk, and walked some I had planned to ride (roots plus hardtail plus lots of riders = bumpy).
Recovery is in order now. That and getting warm. Shower, hot coffe, water, powerade, food (not in that order).
