When I left on my ride this morning, it was 86º at 8:30am. By the time I got home at 10:45am, it was 99º. I drank three full bottles and finished the fourth after getting home, then had two 32oz glasses of iced tea. And it wasn't a particularly strenuous ride-- ~33 miles w/ 1500ft^ at just under 16mph. But every time I would hit a light or otherwise have to come to a stop, the heat... my god, the heat. It just soaks in. Everybody becomes a stop sign runner when it gets near 100º.
During my century on Saturday, I headed out at 55º. I drank half a bottle in 45 miles. Between mile 75 and 110-- when it had gotten into the mid 90s (not helped by the fact I was riding away from the coast,) I drank about 3 quarts (4 bottles.) So yeah. Not the hills or the lack of sleep (hey, I got almost 6 hours last night!) or the fact that breakfast was just a bowl of Frosted Mini Wheats. Heat will drag me down faster than an anchor.
