TRI IT YOUR WAY (VIRTUAL CATEGORY)
Can't make it in person? No Problem!
Here's how Tri It Your Way works:
Pick your triathlon activities! Remember, you can either swim the 400 yards or choose another activity to do for 10 minutes. The bike needs to be at least 10 miles and the run needs to be at least a 5K (yes, you may go over, but not under!).
SAFETY FIRST! Make sure you are taking all the safety precautions when swimming, biking, and running. This means not swimming alone and following all the rules of the road (or trail). Just like all the precautions you take when training or racing an event, we want you to be safe.
Record each activity with your watch, or phone, or bike computer.
Document your tri! Whether it’s someone taking pictures of you “racing” or stopping for a selfie mid-run. We want to see you in action! Dogs, kids, partners, friends (socially distanced, of course) are encouraged to join in with you!
Go to our event page and post your “race” data and your pictures. OR email your pics and race data to [email protected].
USAT SANCTIONED
Results will count toward national and regional rankings. All USAT rules and regulations will apply. Racers are subject to time penalties or disqualification for infractions of USAT rules.
You are required to have either an annual or 1-day (Bronze) USA Triathlon membership in order to race in any USAT-sanctioned event. Non-USAT members will be required to purchase a one-day event insurance license from USA Triathlon. Costs: $14.99/sprint, $24.99/olympic, $9 per relay team member, $10 for youth.
MASSACHUSETTS STATE CHAMPIONSHIP
This is a 2026 USA Triathlon State Championships Ranking Point Event. Residents of Massachusetts can earn points which — combined with results in other qualifying races — will be totaled by USA Triathlon at the end of 2026. Note: you must participate in at least three qualifying races to be eligible for State Champion.
EVENT INFORMATION
After 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 solo or with a group of your friends (2, 3 or 4 persons), the objective is to use your wits and fitness to scramble your way (including 92 steps built into a cliff) to the finish.
THE COURSE
Athletes will receive laminated maps that have checkpoints pre-marked before the race. You will navigate between checkpoints using the map and compass. Teams must check in at all checkpoints and the finish line together. Segments will be categorized as either a run, bike, or swim/paddle discipline. Keep in mind that you may have multiple running, biking, and swim/paddling legs that alternate throughout the race. Also, unlike a relay, 2, 3 or 4-person teams compete together the entire race. This is a point-to-point race, there is no central transition area so plan accordingly.
HOW SHOULD I PREPARE?
Prepare yourself for this event by training to be capable of trail running and biking for two-plus hours. There will be no more than four swim segments, and each swim segment will be 1/2 mile or less. Paddle segments will be longer. Biking elevations range from -5% to 8% grades, running elevations up to 18% grade. You can choose between swimming or paddleboarding. Bring your own, or a limited supply will be available to rent. Be prepared for a mile+ of total paddling or 3/4 of total swimming. Be prepared to read and follow the supplied trail map. There will be four race categories: solo, two-person, three-person and four-person. All members of a team race the entire course together, remain in close contact and finish at the same time.
DISTANCES
Be prepared to:
Paddle 1 - 1.5 miles or Swim .5 - 1.0 miles
Bike (steep hills) 5 - 10 miles
Run (technical trails) 4 - 6 miles

May the fastest... and smartest... teams win!
