With duathlon, two disciplines push you in completely different ways. Duathlon rewards athletes who refuse to specialize — and if you've ever wanted to know what your legs can do after an all-out bike leg, this is your sport.
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
