Racer Information

The concept is simple, though not easy – you will perform the 0.31-mile loop up and down Tut Hill (grassy part) 100 times. This is roughly 90 feet of elevation gain and 90 feet of elevation loss. Trekking poles allowed. No Teams. No Whining. Route will be well marked. Free Will Donation Registration Fee | In lieu of a registration fee, entrants will pledge funds that will be split between the winning runners’ charities. Tax Deductible Donations/Pledges need to be complete by using this link through our fiscal sponsor Falls Area Singletrack –TutHell — Falls Area Singletrack (FAST) on the TutHell50k.com website. You must use this link so we know that the dollars are for this event. Runners should honor their pledge before race day. Falls Area Singletrack graciously offered to help as fiscal sponsor. They are not a part of the management, operations or any aspect of this race other than helping us get pledges/donations to the final destination.

After the race when male/female champions are crowned, their charities will be sent half of what was raised/pledged/donated for the race. The goal for 2027 TutHell 50K is $10,000 ($5,000 per charity).

All Entrants are asked to stay until the last runner has either dropped out or missed the 12 hour cutoff. This race is about building community, fellowship and supporting one another.

There will be a fully stocked aid station at the top of the hill by the bathrooms/storm shelter. Runners are encouraged to bring their own race fueling.

Runners are asked to bring one support person to help them throughout the day. Support people have access to snacks.

Race Course – You will start up by the large tree close to the bathrooms at the top of the hill, follow the single track down the hill to the flat grassy part and then come up the right side of tut hill up to the two little trees where you will go left back to the start.
