Huff, puff...the saga continues...
Cut my ride short today because it was about 90 degrees in the sun, there was a steady wind from the south (which, naturally, was where I was headed), and I just got wiped out. Came home and went to bed after 8.5 miles. Oh, well. Next time.
I have a real problem with hot weather--which for me is anything over 60 degrees Fahrenheit. Always have had....
I'll have to make sure I carry two water bottles on my bike till it cools off again in October, and just take it easy as I build back. No point in killing myself, for I don't think I'd ride very well afterward.
