About the Event

Prepare for a true mountain showdown at the Tenacious Ten Hour Endurance Challenge on Saturday, 9th May 2026. This relentless test moves to the iconic slopes of Mynydd Troed in the heart of the Welsh Black Mountains, where you’ll battle for 10 hours on a punishing 4.3km (2.6-mile) technical loop. More than just a race, it's a strategic gauntlet where you choose your direction after the first clockwise lap, mastering steep ascents with "false summits," technical descents, and rewarding 360-degree summit views over the Brecon Beacons and Llangorse Lake. Enter solo, as a pair, or in a team of four for a "last man standing" battle to log the most laps before the strict 10-hour horn sounds. With mandatory mountain kit, a dedicated "Refuel Zone," and a new course record waiting to be set, this is the ultimate challenge for the brave. Conquer the mountain and prove your tenacity.
