From the Organizer
We are pleased to present TriRidgefield and DuRidgefield. First held in 2007, the races wind their way through the bucolic countryside of Ridgefield, Connecticut. There will be a Sprint Triathlon, consisting of a half-mile swim in pristine Great Pond, a rolling 13-mile bike ride, and a challenging 5K finishing run. For you non-swimmers, we will also have a Sprint Duathlon held concurrently with the Tri, consisting of a 2-mile run, followed by the same 13-mile bike ride, and finishing 5K run.
NOTE: For registrations received after May 1, we cannot guarantee you will receive a shirt.

About This Sport
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.
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think.
