East Fork Challenge
Bethel, United States • 12 Sep 2026
East Fork
East Fork is a trail ultrarunning event at East Fork State Park, 3294 Elklick Rd, Bethel, OH 45106, held on September 12, 2026. The event is in its third year and uses a large loop that circles William H. Harsha Lake.
The main loop is about 33 miles and is run counterclockwise. Distances offered follow the loop structure or a separate out and back course:
- 100 mile: three loops of the 33-ish mile circuit
- 100K: two loops of the 33-ish mile circuit
- 50K: one loop of the 33-ish mile circuit
- 15 mile: out and back on backpack and mountain bike trails
The loop course combines mountain bike trails, hiking trails, a small amount of park road, and a substantial section of the Steve Newman Worldwalker Perimeter trail. In August most trails are expected to be fairly dry, but runners will cross several creeks; two crossings could potentially reach waist depth and a rope will be provided. Course features include lake views, single track, a waterfall in a pine forest area, an open field with wild hibiscus, stretches of fast smooth miles on MTB and bike path, and multiple creek crossings.
All entrants receive event swag described as "rabbit swag." Unique awards are planned for finishers, with belt buckles for those who complete the 100 mile distance. Visit the organization's website for the most recent information.
