I have been riding in Orange County for the better of forty-five years. I know about the dog days of summer and our hot, humid, Septembers. We all know to drink a lot of water before and during a hot ride. A preplanned nutrition program keeps my systems going so that my rides are always enjoyed in top form. I am hammering up the first Santiago Canyon Road Grade. It's always a bit of a strain because of the climb just to get there. My Single Speed Caffeine is geared fairly high but I have overcome this by learning to stay on top and just push hard. It is three hundred hard cranks up that short grade. It is hot, and just to get where I was going used six bottles of water. (refills) With two fresh on the bike I was drinking at a measured pace when it all seemed to go wrong. I was sweating into my eyes and couldn't seem to clear them so I doused myself with my second bottle of water. I could see a little better but began to realize that the water on my back was getting hotter. I was getting too hot and I slowed. The water I had soaked myself with was already warm but now it was so humid that it was not evaporating. It was like being in a sauna. Thank God I made it to the top of the hill. It is a fast downhill and the wind felt great, there is a hairy little left hand turn at speed at the bottom and a little uphill right hand turn. A little light downhill and a sharp left, I sped thru the gate and in to Irvine Lake. Right into the lake. It wasn't a big splash, just a gentle dunk. The water was nice and cool. But after a discussion with some Lake employees I got hosed off and sent on my way. The rest of the trip was uneventful except for a lady on a Laguna Beach side street that looked right into my eyes as she pulled her big 70s' van out in front of me. " I don't have to stop for you !" she yelled at me as I rode side by side with her. I was not confrontational, just ended up there to avoid her giant mass. So I passed her and zig zagged down to a safer PCH. Home was only forty easy miles away.
