Yes my body has adapted to a variety of conditions. Weather is less annoying than it used to be, and I’ve learned to enjoy many conditions. My route is overrun with cyclists in good weather, and the additional ones are the least skilled and aware, so less than ideal weather is good for me. Getting wet isn’t always bad, because it rarely rains heavily for the whole trip. I have a complete change of clothes at the office, so if I get drenched, I can dry off and change. It’s possible to ride in just about any heat in the US, with sufficient precaution.
