Even here in Maine it has been hot, hot, and humid as well, but today it was better. Yesterday I stupidly tried to do a 20 mile ride which involved a large, long hill and I cracked big time (I don't know exactly, but I think it was about 90 degrees and 80 humidity.) I got off the bike and could barely stand. ( Yes, I had plenty of water ) I was biking alone, but several friends happened along and rescued me! HOW does one do this at over 100???
