The Walkway Over the Hudson State Historic Park—a 19th century railroad bridge transformed into a long linear park—hosts a weekend full of running in New York State’s Mid-Hudson Valley. Runners of all abilities are invited to take part in one of four flat, fast and scenic races, including a marathon, half-marathon and 5K on June 12. This year’s Walkway Marathon Race Series will also feature the Think Differently Dash on June 11, providing people with developmental and physical disabilities a one-mile race of their own through downtown Poughkeepsie.

The first three marathon options each traverse the historic Hudson River via the 1.25-mile pedestrian bridge. Participants will run along the William R. Steinhaus Dutchess Rail Trail, the Hudson Valley Rail Trail in Ulster County, and the riverside campus of Poughkeepsie’s Marist College. Pre-registration for the marathon options is required with the fees ranging from $25-$75.

Walkway Marathon organizers will again be certified as green by meeting the Athletes for a Fit Planet’s pledge of sustainability to reduce waste related to the event. A Walkway Marathon health and wellness expo—presented by Dutchess Tourism, Inc.—will also be held on June 11 from noon to 8 p.m. at Mid-Hudson Civic Center in Poughkeepsie, New York.

No bikes, strollers, dogs or roller blades are allowed on the marathon. Headphones are also strongly discouraged. Funds from the Walkway Marathon will benefit the Walkway Over the Hudson nonprofit.
