Yes I run but not nearly as much as I cycle. Maybe once or twice a week. I figure it’s a good change of pace, plus I want to be able to run for at least a few miles (without walking) for as many years as possible. If you never run, eventually you won’t be able to.

Other physical exercise I do on a regular bases, and plan to continue doing to the end of my life:

Martial arts training, weight training, yoga, Pilates or core muscle conditioning, and hiking. I also refuse to use a snow blower or a self propelled lawn mower, and choose to shovel or push instead. My rule is to do at least one of the above every day. I keep a simple log, and miss very few days. Like my hero Jack LaLanne would say, the only way you can hurt the body is by not using it!
