Discussions of weather tolerance seem to create ackwardness among cyclists. As if an admission of not wanting to brave the elements is a statement of non-motivation and that the rider will just be sitting on the couch eating donuts. While this may be true, we can thank people from Hans to Lance (and Charmichael) for giving us better ways to get fit. We now know that you can get great aerobic benefit from throttling yourself on your trainer for an hour....Thanks guys...thanks a lot.
