No, we don’t offer refunds or exchanges. Please read our No Refunds, No Exchanges Policy and our Race Cancellation Policy. Do they both suck? Yes. But at least we explain why we do what we do.
Yes, please! If you're not running, we need you on race day! No race of this type happens without volunteers. Please learn about volunteering here.
Due to the enormous success of the vaccination program, the substantial decrease in severe illness, and that the event is outdoors, we suspended the 2021 vaccination requirement. Let's all hope there aren't any funky new variants that come down the pike. This is our COVID policy in case some funky new strain emerges.
Yes, all runners are chip-timed. To avoid trail congestion, we start runners in multiple waves, just three minutes apart. See also: Chip Timing and Seeding.
The first wave of the race starts at 9 a.m. You must finish the race in 3 hours. Security and volunteers are discharged and streets are reopened based on a 3-hour finish, as timed from the start of the last wave. After that, you're on your own. We will keep the marking flags in place for 24 hours, in case you get behind the sweeper, but this is not a race for walkers.
This race is roughly 12% slower than a road race. For the middle-of-the-pack add approximately 13-15 minutes to your half-marathon road time. Top finishers may be half that. The trails vary in their complexity. The Leatherstocking may add 2 minutes/mile to your regular time. Other trails have a few wide flat stretches where you can move almost at road pace. Not many, mind you, but they exist.
You can find the map, description, and elevation chart here. Vertical rise is about 950 feet. The race will finish at the same elevation as the start.
If you're under 18, you need written parental permission. (And frankly, you should also check with your high school athletic coach.)
Absolutely. Running this event carries plenty of risks, which we like to consider features of the trail and the race… and it’s why we have a waiver that bluntly tells it like it is.
Course records for all age groups, if you think you can snag one, are here: Course Records and Data.
Yep. We have engraved tankards for overall 1-2-3. Awards are three-deep for age group M/F, except for 17-and-under and 70+. Overall (1-2-3)17 and under (winner only)18-29 (1-2-3)30-39 (1-2-3)40-49 (1-2-3)50-59 (1-2-3)60-69 (1-2-3)70+ (winner only) Age group awards are based on chip time, but Overall 1-2-3 is based on crossing the finish line first. So if you think you can snag the podium for an overall win, contact one of the organizers to assure first wave placement.
Shirts and bib names are guaranteed to those registering by August 31. For later entrants, shirts will be distributed after the race depending on the number of no-shows that we have. And bibs, obviously, won't have your name. In prior years we had enough shirts for everyone. This year? Who knows? Want to make sure you get one? Don't wait until the last minute to register.
You must have an ID to pick up your bib. You can pick up the bib of another runner if you share the same last name or household. But you must have copies (digital or paper) of that person’s ID. You are strongly encouraged to pick up your race packet in advance atWestchester Road Runner at 179 E. Post Rd., White Plains, N.Y., on the Friday before the race, from 4–6:30 p.m., or the Saturday before the race, from 10 a.m–4 p.m. (Westchester Road Runner offers a 20% discount on clothes and 10% on non-sale shoes to registered runners.) Pickup on race day is at theThomas Paine Cottage Museum at 20 Sicard Ave., New Rochelle, N.Y., from 7–8:30 a.m. Expect lines. This is the staging area for the race.
Yes, bag drop is available right by the start line. Bags will be brought to the finish. Please don't leave valuables in the bags as we are not responsible for them.
This race is semi-supported. There are only three water/aid stations: Miles 4-ish (Mamaroneck), 7.5-ish (Saxon Woods golf club house, Scarsdale) and 11-ish (Eastchester). If you want a sports drink, gels, energy bar, etc., you should carry it. And dispose of the wrapper properly; do not litter on the course/trail. Each station will also have medical attention courtesy of Empress EMS, and a medical tent will be at the finish courtesy of Montefiore New Rochelle. Toilets are at the start, Mile 7.5, and the finish.
Please hold used gel packs or energy bar wrappers for the trash boxes at the water stops. We do not have a clean-up squad to pick garbage up off the trails. You get two points for sinking each cup or gel wrapper into the box. Points are non-redeemable.
No — headphones are banned. Sorry, but this is a high-risk activity and people must be keenly attuned to those around them that might need to pass on narrow trails.
No — dogs are banned. Sorry, but they are a tripping hazard on narrow trails and not permitted in the finish area either (high school policy, not ours). Blind runners (yes we had one!) who wish to use a guide dog should contact Race Director Eric Turkewitz.
