Kal-Haven Trail State Park is a 33.5-mile crushed limestone path (former RR bed) connecting South Haven and Kalamazoo. The trail meanders through wooded areas, past farm lands and over rivers and streams. Trail highlights include a camelback bridge and covered bridge. Each year since 2010 the Kal-Haven Trail Run (race) has taken place along the length of the trail. Solo course records are equivalent to FKTs for the route. Detailed run results and records are here.
