The Hyannis Triathlon is a USAT Sanctioned event.

Races for athletes.

Organized by athletes.

New England Endurance Events is a race organization staffed by triathletes, cyclists and runners who know what a great race looks and feels like. We believe any running race, triathlon, duathlon or adventure race should be challenging, scenic, organized — and fun!

Our races provide great experiences and festive atmospheres — while paying attention to the important details that paying athletes expect.

How much so? Of the 22 triathlons nominated as “Best in the World” for the 2018 Triathletes Choice Awards, three belonged to New England Endurance Events. Our race director is USAT-certified, much of our staff has decades of race organization experience, and local charities benefit from each and every event.

Just try one of our races this year!
