What do you do when you're running with a group of people, say, in a race, and you realize you have a wedgie? Pull that thing out and keep on truckin', says Runner's World magazine's "Ask Miles" columnist.

Miles deals with embarrassing issues all the time and offers each month his best advice for avoiding all sorts of fitness-related humiliation. In the December 2007 issue of Runner's World, Miles responds to reader Megan J. of Lake City, Florida, who wants to better handle her own embarrassing running moments.

Using the Miles Embarrassing Situation Scale (MESS for short), Miles says the wedgie is a no-threat scenario. Deal with it and be done, he says. He ranks below-the-belt sweat as low threat and recommends black shorts because they camouflage the sweat. He assigns passing gas while running the label of high threat and suggests runners just pass the gas and move on. If you must do it again, drop back and tie a shoe, says Miles.
