Notes
Two 30 min. races, both had 50 person fields. The course was really technical with only one real stretch that was only about 150m.
First race. I couldn't really pass anyone except for maybe one guy each lap on the long stretch. I started to move up with about 10 minutes to go, but with 4 laps left I was in tenth and a dude crashed in front of me, so I took the free lap. When I jumped back in the back of the pack, there wasn't enough time to do much, so I just finished about 20th.
The second race started about 10 minutes later. This time I started in about 10th place but every once in a while someone would pass me and I couldn't pass anyone back. With about 6 laps to go I was at the very back of the pack which only had about 25 people left. I pretty much just hung in there for the rest of the race.
