My back has been problematic for years. Monday morning my back attacked me. My wife had to help me put on my socks. I was gimpy for another 3 days. I managed to eek out 12 miles Monday night. It was my coolest ride of the year @ 50° F. We don't get real cold here in Houston, but below 40° is difficult for me. I've ridden down to 34° but that was once and only 6 miles, but it was a milestone for me. Anyway it feels as if the fates are plotting against me. Rainy weekends and a bad back are not helping my training at all. For the truly curious, that is a new commode seat shoved into my Arkel Bug pannier.
