East Fork 100 Mile / 100K / 50K / 15 Mile

Organized by Empower Ultras, this is the third annual race at East Fork State Park near William H. Harsha Lake in Bethel, Ohio. The event offers four distances and uses a mix of mountain bike trails, hiking trails, a small section of park road, and portions of the Steve Newman Worldwalker Perimeter trail.

The main loop is approximately 33 miles and is run counterclockwise. The loop format assigns distances as follows:

  • 100 mile
  • 100K
  • 50K
  • 15 mile

Runners complete one loop for the 50K, two loops for the 100K, and three loops for the 100 mile race. The 15 mile course is an out and back on smooth backpacking and mountain bike trails. In August the trails are generally fairly dry, though the route crosses several creeks; two crossings could potentially reach waist depth and a rope will be provided.

Course scenery includes lake views, single track, a waterfall in a pine forest area, an open field with wild hibiscus, sections of fast smooth trail and bike path, and multiple creek crossings that provide cooling opportunities. Finishers receive unique awards and all entrants receive branded rabbit swag. Belt buckles are awarded to 100 mile finishers. Visit the organization's website for the most recent information.
