OK so this isn't the most inspiring bit of experience sharing and it will probably elicit reactions ranging from laughter to "oh that's disgusting!" but since I am chronicling all my experiences I don't see why this should be left out.
One of the most well known but least talked about scourges, almost exclusively among male distance runners is chafing. What is chafing you ask? It's when your body constantly rubs against something leading to wear and tear. In a distance runner's case, chafing mostly revolves around nipples. Yes remember even us men have them. Right now, it's becoming a major pain in the ass problem for me. Think about the pain if, when you step into the shower, you have to cup your hands around your nipples so the water doesn't directly hit them? They burn, they bleed and they pain like a kick in the nuts. There's really no "cure" as such because as you run, your nipples will chafe against your singlet, friction leads to skin tear and eventually bleeding and more tearing. All one can do is lube up pretty well, Vaseline is something I haven't tried but something which I intend doing right away. Applying band aids or tape is also something people recommend. I'll keep that as Plan B. But for now all ye men who shall run, remember to guard those two tender spots on your chest.
