I've ridden all over the US and Europe in all sorts of winds. Two were quite memorable. In one race we had two bikes and the bike/roof rack ripped off the top of the follow car and deposited a hundred yards off the road. During RAAM one year we had a tornado on the ground about 5 miles from us. I have no idea what the wind speed was but it was a tail wind and we were flying! A Sheriff stopped us and suggested we might want to pack it up and wait it out but we decided to take advantage of the little push we were getting.
