Yes, 2012 had temps above 100° three days in a row. Century day I started at 0430 to beat the heat, and some of the wind. For me the wind hit just before I entered the Karras loop. I normally ride 20 mph on the flats, but due to the wind I struggled to get 14 mph. Beekman’s root beer float was never more appreciated.
Fortunately, I am used to the Las Vegas heat, so as long as I have water and a breeze I do OK. The killer is when I go up a challenging hill with wind that matches my speed and direction. The ambient heat an body heat add so it feels like a sauna.
