EVENT INFORMATIONAfter five successful years as one of the most difficult sprint triathlons in the world, The GutCheck 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 will be different — and no one knows exactly what it will be until shortly before the race. Just know that it will be an endurance workout you won’t soon forget! WARNING!This is a race for intermediate athletes. Expect cold water, steep hills and difficult cliffside running trails paved with tree roots. While there will be emergency medical support on-site, all participants race at their own risk. HOW IT WILL WORK:Until shortly before the race, all you’ll know about this year’s GutCheck is that it will combine running, cycling, navigating and water crossing (paddleboard or swimming) in Nickerson State Park. You will present yourself at designated checkpoints along the way. Expect a finishing time of 1 to 2 hours. Whether you compete so
