102 is pretty warm, but if you're careful it may be rideable. The only reason I say that is that I hit some pretty hot weather when I rode cross-country back on 2002 - as in many days where it was over 100 degrees. I was still riding 55 to 75 miles a day, in spite of the heat. I was also drinking a lot - a combination of water and Gatorade. (OK, OK, I may have been a bit crazy. But I was happier continuing to move across the country than I would have been sitting still somewhere in those temperatures.)

If you're going to ride in the heat, make sure to pay extra attention to your body, and stop if it tells you to stop. And make sure you are drinking enough.
