Tuscazoar 100
Dover, United States • 5 Sep 2026
Tuscazoar Endurance Race
The Tuscazoar Endurance Race is an ultramarathon held at Camp Tuscazoar in Dover, Ohio. The event uses a 25 mile loop and offers multiple distance options. The course is about 95% trail, remains mostly on camp property, and includes a single 5.5 mile section on private land. The current layout was adopted after changes in 2024.
Distances offered:
- 100 Mile
- 75 Mile
- 50 Mile
- 50 Mile Night
- 25 Mile
- 25 Mile Night
Cutoff policies vary by distance: the 100 and 75 mile races have a 34 hour cutoff, the 50 mile 32 hours, the 25 mile 31 hours, and the night 50 and 25 mile races 21 hours. All runners must begin their final loop by 8am Sunday and the course closes at 4pm Sunday. Runners may change their registered distance before their race start; after the race begins a change results in a DNF for the original distance.
The race is cupless; runners must carry their own hydration and a reusable cup for aid station service. Drop bags are accepted at the main aid station inside Kimble Hall and at the Tuscazoar Preserve aid station. Pacers are allowed only for the 75 and 100 mile races with restrictions on where and when they may join. All finishers receive awards; belt buckles are given to 100 and 75 mile finishers and medals to 50 and 25 mile finishers. Overall and age group awards are also presented.
