A couple of weekends ago, I was compelled to do my birthday ride: 61 miles on my 61st birthday. Been doing that at least since I turned 50, and I suppose I'll continue until I can't. I offer the compulsion part of that because it was low 40s and raining for about the first 30 miles or so. Not my favorite weather to ride in and right between getting really sweaty with dedicated rain clothes and getting cold and damp without dedicated rain clothes. I went without and managed not to get hypothermic and then warmed up once the rain stopped. If it had been another day, I probably would have stayed home. But I ride plenty in the rain between commuting and getting caught in a shower on a long ride (somewhat inevitable in the summer around here).
