Black Diamond Express Trail Race

The Black Diamond Express Half Marathon & 5K is a small, community-driven race held each August on the Lehigh Valley Trail in Mendon, New York. With around 100 runners and a 30% repeat rate, it's a race that runners return to year after year. The course is a flat, USATF-certified out-and-back on a converted railroad bed, shaded by trees and offering a peaceful forest setting. One runner calls it 'a nice out and back run in the woods' — a perfect description for this low-key event.

The race starts at the Mendon Youth Baseball Fields, with easy parking and plenty of volunteers to guide you. There's no time limit, so it's ideal for beginners or those looking for a relaxed long run. The field draws from about three states, giving it a local feel. After the finish, runners enjoy refreshments and healthy snacks, and half marathon finishers receive a collectible ceramic medal — a unique touch. Registration at $50 includes a long-sleeved t-shirt or mug, making it an exceptional value.

Whether you're seeking a PR-friendly trail half or a scenic, well-organized race to kick off the fall season, the Black Diamond Express delivers. It's a hidden gem that combines small-town charm with a well-run production, earning rave reviews from those who discover it.
