We had some moments where we were moving pretty slow - one fall over when he wasn't able to clip out - but overall it wasn't bad. I don't recall much wind, but maybe I just blocked it out. haha. He kept riding after that event and we did 50 at the Napa century, which had some climbs that I was a bit worried about - but he did great on that one too. His power to weight ratio is way better than mine, so if he gets his speed up I will have a heck of a time trying to keep up with him.
