East Fork 100K and 50K

East Fork races are back. This time we are adding two new distances: 100 miles and 15 miles in addition to 100K and 50K. These are Cincinnati only the only 100 mi and 100K races. 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. 15 mile course is out and back on beautiful rolling MBT (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!
