Prepare for a formidable challenge at the Terror of Tammany!, an ultra-distance trail race set to unfold on March 22, 2026, in Columbia, NJ. Nestled in the rugged terrain of Worthington State Forest, this event offers both a 30K and a 50K+ distance, presenting a true test of technical mountain running prowess. The course is structured as a demanding 6.7-mile loop, each featuring approximately 1,750 feet of vertical ascent over very rough, 95% unpaved trails. Runners will navigate steep ascents, enjoy great mountain views, and experience majestic waterfalls along with the sounds of rushing water on the descents. The 30K race completes three loops, while the 50K+ takes on five, with both distances considered as challenging as the infamous Mt. Tammany itself.

The Terror of Tammany! is renowned for its difficulty, inviting seasoned ultra-runners who are accustomed to technical terrain, though a warning is issued that even experienced athletes "may still fall, get bruised, strained sprained and cut". Despite the arduous nature, many consider it "probably one of the most satisfying ultras you will ever run". The start and finish line, located at the Worthington State Forest Campground, doubles as the primary, fully stocked aid station, allowing crews to support runners and providing ample space for drop bags, with the convenience of using personal vehicles nearby. Pacers are permitted for the final loop of the 30K and from loop #4 onwards for the 50K+.

Typical race day conditions in late March include highs around 51F and lows near 30F, with a 14% chance of precipitation. This event is part of the Athletic Equation Trail Series and offers a unique distinction: finish both the Terror of Tammany! and the Mt. Tammany event within the same year to claim the coveted title of "The Terror of Tammany!". Whether you're a newer trail runner seeking an arduous introduction with the 30K or a veteran aiming for an intense mountain ultra, this race promises a memorable and challenging experience.
