Beacons Ultra, Marathon and Half 2026

Nestled within the heart of Wales, the Brecon Beacons come alive each November with the Beacons Ultra and its companion events. This ultra-distance race spans 50 miles through an ever-changing landscape that showcases both the rugged beauty of Welsh mountain trails and the serene stretches along canals.
The Beacons Ultra is a two-loop course totaling 46 miles, punctuated by a challenging ascent up Pen Y Fan on the first loop only. Participants traverse diverse terrain ranging from winding country roads to steep ascents over rocky peaks. The race's unpredictable weather adds an element of adventure; runners have faced everything from crisp autumn sunshine to bitter cold and relentless rain.
The event is renowned for its welcoming atmosphere, where seasoned multi-world record holders share space with first-time ultra-runners. Organizers and marshals are known for their exceptional friendliness, ensuring that every participant feels supported throughout the challenging course. The total elevation gain of 2,258 meters (7,408 feet) tests even the most experienced runners.
For those looking to experience a taste of this epic journey without committing to the full distance, there's also the Beacons Trail Marathon at around 26 miles. This single loop follows much of the ultra route but with a quicker ascent up Pen Y Fan. With an elevation gain of 1,319 meters (4,327 feet), it still offers breathtaking views and challenging terrain.
Completing the trio is the Beacons Trail Half Marathon at approximately 13 miles. This shorter event takes runners through the charming village of Talybont-on-Usk and its surrounding hills, including a climb up Tor Y Foel hill and around the picturesque Talybont reservoir. The half marathon's elevation gain of 543 meters (1,781 feet) makes it an ideal introduction to long-distance trail running.
All three events welcome runners from all backgrounds and abilities, promising adventure and determination as key ingredients for success. Organizers are always on hand to provide guidance and assistance with preparations, ensuring that each participant has the best possible experience during this vibrant weekend of endurance racing in one of Britain's most stunning natural settings.
