The MT. TAMMANY 10
The MT. TAMMANY 10 is scheduled for March 20, 2027 in the Delaware Water Gap area of New Jersey and is organized by the Athletic Equation Trail Series. The event is described as an almost 40.0 mile trail run composed of ten repeated loops that include ten climbs and more than 10,000 feet of elevation gain, presented with an intended completion framework of 10 hours.
The course begins and ends at the Kittatinny Parking Lot Pavilion. Each loop sends runners to the Dunnfield parking lot, then up the Red-Dot trail to the summit of Mt. Tammany. From the summit runners transition to the blue-blaze trail for roughly 1/2 mile, follow a left turn while staying on the blue-blaze route down Mt. Tammany, cross the river, and return to the Dunnfield parking lot to begin the next ascent. The sequence repeats for a total of ten loops.
At the conclusion of every second, fourth, sixth, eighth, and tenth loop runners must return to the Start/Finish Pavilion for check-in and loop verification. The organizer notes that no aid is to be provided by crews in the Dunnfield parking area. The course includes steep trail sections, mountain views on climbs, and waterfalls and rushing water on descents; the organizer warns of possible falls, bruises, strains, sprains and cuts on this terrain.
