NYC Cup Finals - Diamond Mountain Classic Road Race
About the Event
Experience the breathtaking Diamond Mountain Classic Road Race, part of the prestigious NYC Cup Series, on Sunday, September 20, 2026. This race offers an unparalleled runner's journey through the scenic landscapes and challenging terrains of Harriman State Park. The course begins with a steep descent from the Lake Welch parking lot, followed by rolling hills at Tiorati Brook Road that test your endurance. As you progress to Seven Lakes Drive, the terrain becomes flatter but no less demanding, leading up to a slight uphill before reaching the finish line in Lake Welch Parkway. Race organizers have meticulously mapped out this route with clear signage and marshals stationed at key intersections for safety. Moto pacers will be available throughout the race, ensuring you stay on track and pace yourself wisely. Police assistance ensures smooth navigation through busy intersections. Photo journalists capture every moment of your journey, providing memories to cherish long after the race is over. Convenient start times cater to a wide range of abilities, with each field starting at designated intervals. Race officials encourage early arrival to familiarize yourself with the course and set up for an optimal performance. The event offers more than just competition; it's a celebration of cycling culture. Enjoy the atmosphere as fellow racers pass by, and take in the stunning views of Lake Welch and its surroundings. A feeding zone is strategically placed at the 40.5-mile mark on laps three to five, offering water and gels for those who need an energy boost. After crossing the finish line, head left to return to the parking lot or explore Harriman State Park's natural beauty. The award ceremony starts about 15 minutes after the Cat Pro/1-3 category finishes around 1:30 PM at Lake Welch boardwalk. Prizes will be distributed promptly if you're present; otherwise, they'll go unclaimed. Rain or shine, this race promises an unforgettable experience. Register early to avoid late fees and ensure a smooth registration process. For more information on the course details, download the GPX files from the official website. Don't miss out on this thrilling event! For those who wish to support but not compete, photo/vidio vehicles can join before or after the race without interfering with racers. Vehicles must be registered and follow specific guidelines. The Diamond Mountain Classic Road Race is a testament to the spirit of cycling in New York City's surrounding parks. Whether you're aiming for top honors or simply enjoying the ride, this event promises an exhilarating day out on two wheels.
