I have a new mystery...I noticed getting to the 20 mile and beyond that there are new factors to consider. One is the hip soreness. But the thing is that I have had problems with chaffing now, which is a new thing to me. I guess the mileage and sweat combination are taking its toll. Thighs, toes, nips and my arm where I hold the ipod strap on my arm.
I think I need a visit to the running store for some lube.
I went shirtless a few days ago for a 10k and believe it or not, when I got back, my nipples were feeling sore n chaffed! What? A strange mystery, since there was nothing but wind touching! Theories?
