One of the locals asked if I wanted to join his cycling club. They're a bunch of guys whose median age is 44, who plow through a given stretch of woods when the moon is full. I thanked him for the invite, but turned him down. I would have jumped at the opportunity in my 20s; in my 40s it sounds like a short path to humiliation and serious injury.
My winter cycling consists of 15 minute stints on a magnetic resistance trainer, usually doing variations on sprints and only occasionally working a 20-plus minute aerobic spread (i.e., dying of boredom). Since I'm not climbing in and out of the saddle to navigate hilly terrain, I am discovering that the Jake is just a little long for my grasp: my shoulders and neck can get pretty stiff after the longer sessions. I'm hoping a shorter stem (7.5 cm, down from 10.5) will fix that problem.
