I've been going out and riding at 4 for the past few weeks to try and get myself heat acclimitized. After last nights last "workout" before the race this Sunday, I believe I will suffer gloriously.
BTW, we did the scouting report on the course last Sunday too. What time were you there? I ask because we saw one guy solo'ing about two miles ahead in the distance on part of the course and I assumed he was there for the same reason we were.
