Warmed up for this by doing the Central Coast Cyclocross race in the morning, almost made it through that unscathed but managed to slide out on the last lap and show up for this race with some road rash on my right leg.
Took a few laps to get used to the ebb and flow of the pack on the course but felt comfortable enough to move up on different sections of the course. Never felt confident enough to attack - seems like I would move up to near the front on the straights and not have enough energy or space to move up farther by the time we got to a corner. The lap cards went into single digits and then we had a pretty bad crash coming out of the hairpin, I was behind it and caught back up to the group but we were neutralized to permit an ambulance to treat a downed rider.
We got restarted from scratch with six laps to go. Was thinking more about safety versus finishing position and could not get myself to commit to a move that would better my position so just finished with the group.
Someone else must have an identical ANT+ heart rate ID because my maximum heart rate is not 238.
