Black Diamond Express Trail Race
Mendon, United States • 24 Aug 2025
The Black Diamond Express Trail Race, organized by the Mendon Foundation, takes place on the scenic Lehigh Valley Trail in Mendon, New York. The event features a USATF-certified half marathon and a 5K race, both run on a flat, fast, and mostly packed stone dust surface that follows a former railroad bed. The half marathon covers 13.1 miles out and back, starting near the Mendon baseball fields and turning around near Rush, while the 5K is a shorter out-and-back route. The trail offers a beautiful, slightly soft surface with occasional wood bridges and road crossings, supported by volunteers and local sponsors. The race fosters a friendly atmosphere with live music, refreshments, and prizes, supporting trail maintenance and community efforts. Visit the organization's website for the most recent information.
