About the Event

Embark on a legendary, multi-stage odyssey from ocean to peak in one grueling day. The Sea to Summit Triathlon, a premier "bucket list" adventure race, returns on Saturday, July 25th, 2026, challenging elite athletes to swim 1.2 miles, bike 95 miles through the White Mountains, and then run/climb to the 6,288-foot summit of Mount Washington—the highest peak in the Northeastern United States. This is not a traditional triathlon; it's a demanding test of endurance, strategy, and mountain grit, requiring qualification and the support of a personal porter. With a course voted among the world's top five must-do races, it offers an unparalleled sense of achievement. Are you among the serious few who can conquer the ultimate ascent from sea level to the roof of New England?
