River— United States

Spuyten Duyvil 10K

Distance: 10km
Edition update — The 2026 edition will not be run (NYOW announcement).

About the race

The Hudson River at the threshold of Manhattan is a restless, tidal artery, colored by the sediment of the north and the salt of the Atlantic. Swimming here means surrendering to a rhythmic, pulsing current that gains roughly one knot of intensity as it constricts through the narrow passage of Spuyten Duyvil. This channel, separating the Bronx from the island of Manhattan, carries a name rooted in 17th-century Dutch lore—a 'devil's spite' that warns of the treacherous, swirling waters where the Harlem River meets the Hudson’s main flow. It is a place where one must navigate not just distance, but the intersection of powerful hydrological forces that have dictated maritime movement for centuries.

Views from the water

As you push south from the starting point in Yonkers, the landscape reveals the sheer scale of the river valley. To your right, the cliffs of the New Jersey Palisades rise as a jagged, dark boundary, while the Manhattan shoreline unfolds in a series of dramatic geological and architectural shifts. You will pass the site of the former Paterno Castle, a residential fortress that once loomed over the bluffs until its demolition in 1938, now replaced by the residential complex of Castle Village. The area remains physically scarred by the 2005 landslide, a sobering reminder of the unstable earth beneath the Henry Hudson Parkway that required a multi-million dollar stabilization effort. Looking upward toward the horizon, the heights of Bennett Park mark the highest natural point in Manhattan at 265 feet, a geographical pedestal that offers a hidden perspective on the valley you are currently crossing. Further along the route, the medieval-inspired spires of The Cloisters appear to emerge from the greenery of Fort Tryon Park, grounding the modern river transit in a visual echo of European architecture. The course is a direct line through history, passing the site of the 1776 battle where British forces secured the heights, and moving beneath the immense steel span of the George Washington Bridge.

Race day experience

This 10 km journey is designed as a non-competitive, untimed event, prioritizing the flow of the river over the clock. Participants start in waves from the kayak dock at JFK Marina, equipped with mandatory swim buoys. Because the river is an active shipping channel, the logistics involve a carefully managed exit at the Inwood Canoe Club, where the final turn requires a sharp adjustment to clear the ladder. The entry fee covers the necessary support infrastructure, including a professional escort of kayaks, fire department vessels, and Coast Guard monitoring to ensure safe passage through the busy commercial lanes. Whether you are a local or a visitor, this swim offers a perspective on the city that is impossible to gain from the streets. For those seeking different challenges within the same ecosystem, the calendar includes the Rose Pitonof Swim later in the summer, which tests endurance over a different stretch of the city's surrounding waters.

How to get there

Where to stay

Accommodations near the finish line in Inwood and nearby Riverdale range from modest guesthouses to boutique hotels located in repurposed historic buildings. Budget-conscious participants often opt for rooms in northern Manhattan, typically costing between $180 and $300 per night, depending on proximity to the subway lines.

Things to do nearby

The weekend of the swim is ideal for exploring the natural and cultural elevation of upper Manhattan. Visitors can trek through the ancient rock formations of J. Hood Wright Park, which contains its own secluded cave system, or visit the medieval collections at The Cloisters. For those who prefer being on the water, the Inwood Canoe Club offers a community-based look at the local maritime culture. Exploring these nearby historical and recreational sites provides a deeper understanding of the river valley topography that you navigate during the swim.
