Took the XX out a few days ago in the desert heat. 114 degrees! Long story short I lasted about an hour before I was totally drained. Had plenty of cold water in my camelback but the sun just sucks the energy from you. The ride home, street legal in Az with a plate and insurance, back 30 minutes through the desert and then a few minutes down my road lasted forever. I died when I walked in the door and layed on the floor in the AC for 20 minutes. Then a cool shower to lower my body heat. I'm really anxious to start riding daily again but it looks like a few more weeks before the Arizona heat gets within bearable limits, under 102 degrees.
