How often do ya'll fall while on a run, and what caused it? In 15 years, here are mine: twice fallen in the snow cause the snow covered the curb. twice fallen real hard and fast on the right-of-way next to the road because of some circular medal rings (tire pieces?) that trip you around your ankles. They are the devil. Three times while racing - down a hill in a XC race, at the finish line of a fast 3k, and during a Penn Relays 4xMile botched handoff. Once, got tackled by an angry teammate. Once while streaking naked in college while being chased by police. Tried to jump over someone else who had fallen just as he stood up. Never once fell on ice.
