About This Sport
From Endurance Grid's Founder
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.
Three sports, one race — swim, bike, run in sequence, with transitions that are a discipline of their own.
Open water, open roads, and competition with yourself. Cross the finish line knowing what it took to get there.
Triathlon
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think.
