Tarrywile Marathon

Tarrywile Marathon is a trail marathon held in Danbury, United States, in November. The race uses the trail network inside Tarrywile Park, and a half marathon and a 10K start on the same morning.

The course is built around a single half marathon loop. Marathon runners cover that loop twice, while the half marathon field covers it once. A single lap climbs roughly 3,000 feet in total, so the terrain is tougher than the headline distance suggests.

Much of the surface is technical single track of the kind found across the Northeast. Several viewpoints look out over Danbury and the park's lakes. The route is marked with ribbons and signs, and runners are expected to know it and carry a map if they need one.
