Katonah Museum of Art 9 Mile Road Run
This run is perfect when conditions on the trails get dangerous. Park on Reservoir Road behind the Katonah Art Museum and head East. The road turns into Maple Ave. At the stop sign, turn left onto Route 309, the only paved portion of the run, then when you reach Upper Hook Road, turn left again onto the dirt road. Out-and-back will get you 9 miles but you can add some extra by running over the dam.
