Episode 13: Catching up with the Cheetah of bicycling

A bike messenger born in New York in 1960, Nelson Vails went from the streets of the Big Apple to the Olympic track, finishing second in the 1984 Los Angeles games behind teammate Mark Gorski. He's also just one degree removed from Kevin Bacon as a featured two-wheel costar in the 1986 bicycling movie "Quicksilver." Vails retired from professional cycling in 1995 but continues to be involved with the sport as a commentator and amateur cyclist like the rest of us -- except with much bigger quads.
