Love my nipples

Do you know what this is?
It's about the size of a quarter.

This little foam, sticky cover is going to keep me comfortable during the race this weekend.
Yes, I suffer from painful nipple abrasions.

Go ahead and laugh, my nipples won't be chafed this year during Solstice. Last year they bled from my shirt constantly rubbing them. It was all that I could think about towards the end of the race, "Man, my nipples hurt!"
