I started out really well and felt good until the finish of the 2nd lap when I started to feel sick to my stomach. In an effort to stem the nausea I dropped anchor and lost the lead about half way through the last lap. Finally recovered about an hour after the race. Not sure what the issue was. Perhaps it was the onset of heat exhaustion. My legs never really felt bad but I felt on the verge of throwing up for a while there. Lost 5 minutes on the last lap. Limped in 2nd place.
