From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
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 — a great bridge between running and triathlon.
