What do you guys do when you run into a case of runner's knee? I don't know if I have runner's knee for real, but I have had a little soreness the past couple runs. I can still run fine and at top speeds, but figure I should give myself a little time off. I'm also going to get rid of a pair of new sneakers that suspiciously coincided with this discomfort. Anyway, what types of exercises do you do when you're not running so that you do not get fat? I'm not huge into swimming. My local gym's pool is usually chock full of either too serious Michael Phelps types and/or screaming kids. Thanks!!
