There is a point on San Vicente while running West when one rounds a corner and is confronted with — shockingly — what appears to be the entire Pacific Ocean. It is an awe-inspiring sight, even at night. It is at this point, during what is more or less a fifteen mile run, that I usually realize I’ve forgotten to do something to protect my nipples. Aside from the Marathon, this route is the longest I’ve ever run. On little three- and six-mile runs I don’t need to do anything about my chest. On a fifteen mile run, though, thousands of thumping strides will cause a man’s t-shirt to chafe and rub against his nipples until they bleed. The adrenaline and runner’s high will prevent you from realizing how much damage you’ve done to your vestigial mammary glands until you finally arrive home and toss your sweat-drenched clothes into a heap in the bathroom floor. The blisters on your feet, the near-unbearable soreness of your legs and lower back and even arms, the inevitable lingering desire for water … none of these things the next day can compare to the burning pain of having basically rubbed off your nipples. File under: Ouch.
