About the race

Welcome to the 2026 Grindstone Trail Running Festival by UTMB! We couldn't be more excited to have you join us in 2026. Expect some exciting new additions to the race for both runners and volunteers. Grindstone Trail Running Festival by UTMB cannot happen without our dedicated and passionate volunteers. We are eternally grateful for YOU - our Grindstone family!

All volunteers will receive a custom shirt, meal(s), and access to priority registration for next year's event.

We are looking for several specialized volunteers for Aid Station Captains, Sweeps, and SAG Drivers. These positions are considered leading roles and have access to additional incentives for the volunteer incentives program. These volunteers receive a complimentary race entry to any non-sold out UTMB race in North America and Canada.

We look forward to working with you at the Grindstone Trail Running Festival by UTMB this year!

*Note: Shift times are approximate and may change (+/- 30 minutes). We will send exact arrival times for each shift as we approach the event date. The shift times are the start time you should be at your location, not the time you should be checking in to volunteer.

As we continue to work with our permitting partners and finalize race logistics, we will update any necessary time slots accordingly. Those that have already registered to volunteer will be notified of any changes affecting their position.

Volunteer positions are first come, first served. Please email our Volunteer Director, Josh Oppenheimer at josh.oppenheimer@team.utmb.world with any comments, questions, and/or concerns.

There are no shifts available at this time.
