The Ultra - Brecon Beacons
The Ultra is a 30 mile trail ultra held in the Brecon Beacons. The event takes place on technical and scenic trails and is scheduled for 7 November 2026, with a 2027 date listed as 6 November.
The route begins at Georgetown boys and girls club in Merthyr Tydfil and follows the Taff Trail for several miles. Runners then split away to follow trails alongside the River Taff, heading north toward the Brecon Beacons Reservoir. A GPX route file is provided for the course.
There are four staffed checkpoints with water and food: Cwm Cadlen Road Crossing at 6 miles; Pont yr Daf Car Park at 13 miles; Torpantau Train Station at 19.5 miles; and Ffynnondwyn at 26 miles. The cut-off at checkpoint three is six hours after the start, which requires an average pace of about 20 minutes per mile or quicker. The event is cup-less, so participants must bring their own drinking cup.
Compulsory kit includes a fully charged mobile phone, minimum 1 litre hydration, foil blanket or bivi bag, basic first aid kit, torch, whistle, waterproof jacket and trousers, warm layer with hat and gloves, and a bag or rucksack. Visit the organization's website for the most recent information.
