Castle to River Run

The Castle to River Run takes place in the historic Hudson Valley. The 1/2 marathon race takes you up past Osborn’s Castle and down to the Hudson River. The 5K race follow part of Benedict Arnold’s escape path down to the Hudson River and back to the recreation center. The 50k races takes you past both the Castle and Benedict Arnold’s escape path as well as into the Hudson Highlands State Park. Our kids 1-mile takes place right on the recreation center grounds and enjoys the beautiful fall foliage and picturesque views.

Cut-off Times
The 50k has an 8.5 hour time limit, meaning you need to finish by 4:30 pm. This is about a 16-17 min / mile pace. This cut-off allows for runners to finish the race by dusk.

To ensure all runners complete the race by this time, there will be cut-offs at the 4th and 6th Aid Station (these are at the same location).

Runners must be through the 4th Aid Station by 1:45 pm (mile 18.5) and the 6th Aid Station by 3:45 pm (mile 24.5). If you come in after these times, you’ll be pulled from the course.

If you think you’ll need more than 8.5 hours to complete the 50k, we’re allowing an early start at 7 am. Also keep in mind you’ll be on your own the first hour-plus. Aid Stations and Field Marshals may not be ready – so please plan accordingly. Know the course and bring some fuel and hydration.

There is not a cut-off time for the half marathon.
