SOS Cape Cod Race Description

Register here! This event is SOLD OUT for 2021!


Following in the footsteps of the acclaimed SOS Triathlon® in New York, SOS Cape Cod is a point-to-point adventure race using all three disciplines of triathlon to cross 38 miles of the spectacularly scenic Cape Cod National Seashore. Here, you begin your journey with a bike ride, followed by a series of trail runs and fresh-water swims before ending in Wellfleet for a post-race meal and after-party. Due to the rigorous nature of this race there are qualification standards: please read them carefully.


Like the original SOS event, the race starts with a bike leg; which will leave from Mayo Beach on Cape Cod Bay in the village of Wellfleet. You’ll follow mostly back country roads to Provincetown, then to Truro. Racers will leave the bikes with their support person and venture onto the sandy trails of the National Seashore. Total running is 9 miles. Along the way you will encounter glacier-created kettle ponds which will require three swims: each either a quarter or a half-mile. You’ll finish with a one-mile run along a quiet road to the finish line at Wellfleet’s Congregational Church. You and your support person are welcome at a full meal at the after-party and awards ceremony.


As part of your registration for this race, you will need to provide documentation showing you have completed or will complete at least 1 week before the race, one of the following within 30 months of race day: a standard Olympic-distance race in 3:00 hours or less (or adjusted time if a non-standard Olympic); a half-Ironman in 6:30 hours or less; or an Ironman-distance race in 14 hours or less.


Each competitor must designate a support person, or porter, with vehicle to park in designated areas during the race, to be present at the first transition stop to take your bike, and to be present at the finish line.


The SOS Triathlon, founded in 1983 by Don Davis is widely considered to be one of the sport’s most iconic events. Held every September in the rugged hills bordering New Paltz, New York, this eight-stage triathlon (bike-run-swim-run-swim-run-swim-hill climb) attracts some of the world’s best athletes — as well as individually-minded age groupers looking for a challenge unlike anything else. Winning athletes at the 2021 SOS Cape Cod will be invited to compete in the September “2021 Championship” at New Paltz.


It is important to keep athletes, volunteers and staff safe! As guidelines shift for events of this type we will update this race's website page and post to Facebook.
