MORE THAN A TRIATHLON.

MORE THAN AN ADVENTURE RACE.

A UNIQUE JOURNEY ACROSS LAND AND WATER

There are enough triathlons and duathlons out there. How about a true test of your late summer conditioning? After five successful years as one of the most difficult sprint triathlons in the world, The Gut Check was reconfigured in 2019 as a point-to-point adventure race within Cape Cod’s 2000-acre DCR Nickerson State Park. Each year, the course is different — and no one knows exactly what it will be until shortly before the race! The 2025 race filled to capacity in advance of Race Day. Don’t miss out in 2026!
