The Black Diamond Express Half Marathon & 5K starts at 8:00 AM in Mendon, New York, giving you time to settle into your hotel and handle pre-race logistics. Held on August 23, 2026, at 3865 Rush Mendon Road, the event offers two distances: a half marathon and a 3.107-mile option. Entry fees range from $30 to $85 depending on your choice and registration timing. If travel plans shift, you can still participate virtually. This late-August race is ideal for runners looking to fit an event into summer training without the pressure of a major marathon, and the morning start means you'll be done early enough to explore the area afterward or begin your drive home.
