Yes, it does take awhile to get ready for a cooler ride. But I don't mind stopping to peel off things. I can push down my arm warmers while riding, and sometimes I leave them that way! In early spring/late winter, I tend to leave my vest on, just because I like it for the safety part; drivers may not be used to seeing riders in March or April. And yes, at cooler temperatures, wind and/or couds make a huge difference in how you need to dress. I agree with you, though, I don't like riding in hot weather, either. I have built up to it, but mostly I can plan shady rides on those days. But, sometimes you have no control. Last year, we led our 50 mile, hilly ride up to Hollis, NH on a 95 degree and slightly humid day. Though it is mostly shady, the heat, plus 3K feet of climbing just about killed everyone. Praying that this year, when we lead this on 7/16, it's 75 degrees and sunny!
