If you're running in the mornings, it's more important than ever that you learn to er, clear the chute, before you head out the door.
"Bears do it in the woods and runners have to do it before a long run… you know what I'm talking about (it rhymes with 'make a loop')," Bowen Shea says. "Some long-time runners have their bowels trained to evacuate when they wake up, but newer runners have a tougher time clearing the chute. Set your alarm early enough so you can have some vertical time before you start running. Gravity is your friend in getting things moving, as is coffee, which speeds things along for many runners."
Not a java-junkie? Drinking hot water can have the same effect.
