The 2025 SwimRun Cape Cod

Enjoy the majestic beauty of the Cape Cod National Seashore in one of the most unique endurance races. Two distances from which to choose — plus you can race solo or form a team of two.

Brought to you by race directors with an established record for stellar multisport events throughout New England.

There are two distances to SwimRun Cape Cod this year: Medium Course: (approx. 9.7 miles of running and 1.8 miles of swimming across 7 bodies of water), and Short (4 miles of running and 0.75 miles of swimming). A longer course option may be introduced in the future.

Like most swim-run competitions, we welcome solo competitors or teams of two athletes. Standard swim-run protocols and guidelines will apply to this event.

Solo competitors can register for either distance. Two-person teams may race the Medium Course distance only.

SwimRun Cape Cod is one of 12 events in the My SwimRun series of races held worldwide. You can earn a spot in the world championships by winning your class at SwimRun Cape Cod, or by accruing points with each race in which you compete.

For 2025, the championships will be held in Portugal (long distance), Sweden (middle distance) and France (sprint distance). Qualified athletes also have the option in competing at the 2026 championships (event locations to be announced).
