Kapalua, Maui, HI – October
The name says it all: Maui’s prestigious XTERRA World Championship off-road competition tests your self-discipline in a spectacular setting. With a one-mile rough-water swim, an 18.89-mile mountain bike ride, and a 5.9-mile trail run through pineapple fields and forests, it’s anything but easy. And at $500 to enter, it’s also anything but cheap.
