About the event

East Fork 100 mi/100K/50K/15 mi
East Fork races are back for the third year. Welcome to our partner Tri State Running Company! 100 miles, 100K, 50K and 15 miles races are being offered. 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!
