Start/Finish Location and Parking

The start and finish for all racers is at the Philipstown Rec located at 107 Glenclyffe, Garrison, NY 10524, off Rt 9D.

Parking will be at the Rec Center Look for a parking volunteer to direct you to a spot.


The cut-off time for the 1/2 Marathon is 1 pm. This should allow plenty of time for all runners to finish.

There is no cut-off time for the 5k. It’s a beautiful loop to run, walk, or hike at your leisure – all while supporting the Philipstown Rec.

Sweepers and Dropping Out

Please note that if aid station personnel or course sweeper determine that a runner must exit the race, their word will be final!

Please accept that they are acting in your best interests as well as the best interests of the race and all concerned.

If you need to drop, please be sure to drop at an aid station. Tell the race director or an aid station volunteer that you are not continuing.

Aid Stations

There will be one aid station for 1/2 marathon runners that can be accessed twice during the race – at mile 5.5 and mile 8. This is a single aid station that runners will pass while doing a short loop.

There will be no aid station for the 5k. Please plan accordingly.

The 1/2 marathon aid station will consist of basic supplies: water, sports drink, and maybe some fruit and other carbs. We won’t have gels, etc at the aid station. Please plan on taking any supplementary hydration and nutrition with you as you deem fit.

Bag Drop

Please note that we do not offer an official bag drop. But parking is not far from the start and finish so you will be able to reach your car if you need to stash your bag.

You are also free to drop a bag inside the Rec itself or outside near one of tents. Just keep in mind we are not responsible for stolen or missing items.

Finisher Award

All race entrants will receive a finisher’s award t-shirt.

You must sign-up by Friday, October 13th to be guaranteed a shirt in your size.

We will have a limited number of shirts for runners who register after the 13th which will be given out on a first-come-first-serve basis.

Refund Policy

The Castle to River race will be held rain or shine. As this is a not-for-profit fundraiser for the Philipstown Recreation Department, we cannot provide refunds to participants.

Only in the event that the race is canceled by the organizers (The Friends of the Philipstown Recreation Department) will refunds (less the non-refundable Ultrasignup service fee) be issued.
