Welcome to the Dickerson Mine Endurance Challenge, an exhilarating 3-hour mountain bike (MTB) race that invites both seasoned endurance riders and newcomers alike. The event promises thrilling competition with a focus on completing as many laps of the challenging course within the given timeframe. The heart of this challenge lies in its simplicity: ride hard and fast to rack up more laps than your competitors, earning you the title of King or Queen for another year until next time's showdown. You'll be crowned at the finish line where a special throne awaits, symbolizing your victory. Your entry into the race is as easy as bringing along your bicycle—no license required. Preparation and registration take place at Marty’s Reliable Cycle located at 1164 Route 10 West in Randolph, New Jersey. Registration opens from 7:30 to 8:30 am on event day, ensuring ample time for last-minute preparations or pre-ride inspections of the course. The starting line staging will begin promptly at 8:45 am. The race itself commences exactly at 9 am with a mass start, allowing participants to choose their own position in the pack; early arrival is encouraged if you wish to secure a prime spot. The 6–7 mile singletrack course offers a mix of varied terrain and flowy sections that will test your skills and stamina. Navigating the course relies on clear arrows rather than GPS, ensuring a more authentic riding experience. For those eager to see what lies ahead, the detailed map for the 2026 edition is available online. Spectators are welcome in an exciting zone near registration, adding to the vibrant atmosphere of the event. The race will conclude at noon with results rolling out live as you cross the finish line. A mechanical support point and water stations await at both start/finish zones to ensure your safety and comfort throughout the course. Post-race festivities include a complimentary pasta meal from 12:30 pm, followed by award ceremonies for top performers in each category. Awards will be handed out promptly at 1:30 pm, with medals and crowns reserved for the fastest male and female participants who claim the ultimate title of King or Queen. Rain or shine, this event promises to deliver an unforgettable experience filled with competition, camaraderie, and adventure on New Jersey’s finest trails.
