My question is dumb and intimate; what if anything are you supposed to wear under lycra?
With my 3rd marathon in 3 weeks I suffered from chafing for the first time on my 20-miler on Sunday. So I bought some men's Nike lycra shorts, but was disappointed to find they're not really built for men if you see what I mean ;-)
All in all I couldn't see me doing more than 10 miles without the lycra itself causing chafing. But knickers, lycra AND running shorts seems a recipe for overheating. Thoughts?
