The Thunderbunny Trail Races take place at Strouds Run State Park in Athens, Ohio on May 9, 2026. The event offers three distances:

- 11K
The event is held under special use permits from the Ohio Department of Natural Resources. The overall field is limited to 400 combined participants; a waitlist is used if the event reaches capacity.
Course, cutoffs, camping and entries
The courses use predominately singletrack trail and include paved and gravel sections. Terrain summaries:
- 50K: 3517 feet elevation gain, 29 miles singletrack, 1 mile gravel, 1 mile pavement.
- 25K: 1608 feet elevation gain, 16.1 miles singletrack, 1 mile pavement.
- 11K: 610 feet elevation gain, 5.84 miles singletrack, 1 mile pavement.
The 50K and 25K share aid station cutoff rules with a 9-hour course cutoff; the Dow Lake Dam aid station is the key hard cutoff location where longer-distance cutoff requirements begin. The 11K does not have a hard cutoff and is described as suitable for hikers. Group camping is offered for a fee with primitive amenities; individual campsites are available through the park. Registration opens December 1, 2025 and closes May 7, 2026, with online registration only. Visit the organization's website for the most recent information.
