There are enough triathlons and duathlons out there. How about a true test of your season-end conditioning? After five successful years as one of the most difficult sprint triathlons in the world, The Gut Check was reconfigured last year 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. Know that the 2021 race morning will be one that you won’t soon forget!
