After taking a rather long break, I've started running again. So far, it's going pretty well. I can run for 20-25 minutes without stopping, and I'm not really feeling any pain. Not bad for someone coming off a long period of almost complete inactivity. However, the problem I'm having is that I'm getting horrible chafing on my inner thigh. I didn't really think about that and just threw on a pair of windpants over my boxer briefs, but they chaf horribly. What do you wear to get around this? Are compression shorts the best way to fix it, or is something else better? Any particular brands to watch out for?
