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. Route Map below.

Free Will Donation Registration Fee

The donations will be pooled in a Charitable Fund and your donation will be fully tax deductible. Runners should honor their pledge before race day. The link for this Charitable will be provided in the coming weeks. After the race when male/female champions are crowned, their charities will be sent the funds from the Charitable Fund. The goal for 2026 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 10 hour 7-minute 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. Official Race Chip Timing and Live Tracking through UltraSignup.
