East Fork returns with new distances: 100 mi, 15 mi plus 100K and 50K

East Fork races are back for the second year. Welcome to our partner Tri State Running Company! This time we are adding two new distances: 100 miles and 15 miles in addition to 100K and 50K. These are the only 100 mi and 100K races in the Southwest Ohio area, don't miss out! The course will travel counterclockwise on beautiful and challenging trails around the William H. Harsha Lake in East Fork State Park. The entire loop is 33-ish miles, so runners will do three loops for the 100 miles, two for the 100K, and one for the 50K. The 15 mile course is an out and back on beautiful rolling trails (to the first Manned AS and back). The course will follow some mountain bike trails, hiking trails, a tiny bit of park road and a fair amount of the Steve Newman Worldwalker Perimeter trail. In August most of the trails should be fairly dry but you will cross several creeks, giving you a chance to cool off (they will feel amazing in August)! Throughout your journey you will experience some beautiful lake views, glorious single track trails, a waterfall in a beautiful pine forest area, an open field and some refreshing creek crossings. This is an experience you don’t want to miss!

Aid Stations and Distances

Our course runs a little long. More fun! No worries, the 40 hour cutoff allows most runners to complete the course as long as they are moving forward with purpose. The course is a rolling course. There are no significant climbs, but lots of smaller rollers that can be taxing. There are gorgeous views of the lake, beautiful wooded areas, and meadows that, although flat, can be hard in the open sun. There is also some running on the shoulder of the park road, but majority of the course is on the trails.
50K is roughly 33.7 miles and 100K is about 67.4 miles. Just one extra mile for 100 mile distance (101.1 mi).
