First really hot day of the year and I think I can go for a 2 hour ride. I have no sense of my limitations until they hit me on the head. I seriously bonked at 24 km after 52 minutes. But I was making great time.
I also learned that my bike computer's thermometer only goes to 99°F. I am switching to °C so I don't have to worry about that unless I ride on Venus.
mostly sunny and 91 to 99°F+, winds 10-15 mph S to SW
