Topo Trail Marathon Races

The Topo Trail Marathon is an annual trail running event held at East Fork State Park in Ohio. It features three race distances: a 6.55-mile quarter marathon, a 13.1-mile half marathon, and a 26.2-mile full marathon. The course consists of a single 6.55-mile loop on 100% singletrack mountain bike trails, with runners completing one to four laps depending on their race.

Aid stations are located at miles 2, 4.5, and the start/finish, offering water, Hammer nutrition products, bananas, and salty snacks. The event provides professional chip timing, finisher medals, long-sleeve race shirts, and a friendly, supportive atmosphere for trail runners of all levels.
