As I was getting towards the end of my 11 mile run last Sunday, my nipples were getting sore. I had heard about this happening. They were rubbing against the inside of my shirt. The shirt I was wearing was a Nike Sphere Dry shirt that has kind of a rough texture. It supposedly has more surface area for moisture to evaporate, but meanwhile it became increasingly more and more uncomfortable as I ran. I am going to run a half marathon this coming Sunday, and need to find a solution. I had ordered another shirt which came yesterday. I was hoping it would have a smoother material, and be kinder, gentler to my nipples, but alas, it was a compression fit thing that I am not ready to be seen in public in. I may go down to Dick’s Sporting Goods tonight and buy yet another Nike shirt, but a regular Dri-Fit shirt, and not the Sphere Dry. They seem smoother. I have read that some guys put bandaids over their nipples, but that seems kind of weird!
