About
The MT. TAMMANY 10 is a trail ultra held in Walpack Township, New Jersey, on March 20, 2027. One distance is on the program, a 40-miler, and it starts in the dark at 5:45 AM on Mount Tammany.
A pre-dawn start on mountain trails means a headlamp for the first hour and a plan for the temperature swing that follows sunrise, when what felt right at the start becomes too warm. Forty miles of climbing takes far longer than road runners expect, so build with long back-to-back weekend runs on steep ground, practice descending without wrecking your quads, and get comfortable hiking uphill at a steady rhythm. Carry your own food and water between aid stations, and set an early pace that feels almost too easy, because the second half of the day decides the result.
