What kind of a lunatic runs in a cotton top?!
Either medical tape or a compression top will stop it. A proper running top will help but I found that by 15km I get rubbing even in the nicer running tops (2XU in my case).
Hurts like hell for a while, good effort to make them bleed, I've only ever got to the very sore stage.
My comment was meant to be light hearted, honestly. Don't you find that cotton tops feel awful once they're saturated with sweat and start to cling to you? Anyway, I don't see how you can say you never have any problems with them, given the fact that you nearly lost your nipples that dayEh me, and I never have any problems with them. Forgot to tape nipples.
Would have been exactly the same in a synthetic top.
Sounds like a big improvement over the pain you were getting after just 2km, though, so that's a positive sign. My (admittedly limited) experience suggests that you should just take it easy and don't rush anything. Pay attention to the signals your body gives you; will tell you if you're pushing too hard too soon.I'm crossing my fingers, managed a fully pain free 5k, first time since 17th January. Distance wise its low but its baby steps atm and ill take any positives going.
