Congrats man. A marathon effort :)
Never heard of bleeding nipples though. Damn, that is some hard core chafing! You better get some better protection for those delicate man boobs next time.
EDIT : Apparently it's quite common and many runners put bandaids over their nipples. Who knew?
Well I clearly didn't.... Well I did, but never thought it would happen to me.
Imagine constant sandpaper + pin pricks constantly for the last 5 miles. Some people pay lots of money for that kind of crazy shit.
