Afton Trail Run
The Afton Trail Run was established in 1994 and is now one of the oldest, largest and most competitive trail races in the country. The race(s) consist of a hilly 25K loop (two loops for the 50K), winding through the state park’s trail system. The race is held 100% off road, primarily on very runnable single and double track trail. There are 7 long climbs per loop, rising from the river valley and down again with a good mix of rolling and flat terrain between the hills.
