Living in the desert southwest (Tucson area) does pose a few issues.
Rode 20 miles today starting at 9 a.m. It was already in the 90s with mediun humidity (around 30%).
Less than 2 hours later my computer on the bike registered between 108 and 114 degrees. Agree that's the temp in the sunshine and that'shere I am riding; shade is almost zero out here except for shade from a telephone pole or a big cactus.
Actual high temp for the day at the airport (in the shade) was only 101.
Drank one 8 oz bottle of cold/iced water.
Have ridden in 98 degrees with 98% humidity in Maryland; no fun. Give me the desert anytime!
