It was kind of an eye-opener when, early on, our rando group went across the road to eat after a ride, and Dan, one of the foremost long-distance riders around, ordered a salad. He was all buff and everything, riding as many miles as anyone around, and still having to watch his weight. I've gotten in more miles the last couple of years than ever before, and still have gained weight doing it. So it's not just you. And it's not just water, either.
