Beacons Way Ultra 100km

Beacons Way Ultra 100km : Race Across Bannau Brycheiniog

The Beacons Way Ultra 100km is a 100 kilometre (62 mile) self-navigation ultramarathon across the Brecon Beacons National Park on Saturday 25 July 2026. The route follows the official Beacons Way with 3,178 m of ascent, takes in Pen-y-Fan and the Carmarthen Fans, and has 250 places. The event awards UTMB Performance Index and ITRA points and can act as a Western States 2027 qualifier for runners who finish within the specified time.

The course uses six manned checkpoints that provide drinks, hot food at indoor stops, vegetarian and vegan options, and medical cover. Checkpoint cut-offs are strictly enforced and every runner must check in at each checkpoint. Dropbags may be taken to Checkpoint 5 and to the finish; size limits and collection rules apply.

Entry is by application. Applicants must be at least 20 years old at race time, declare suitable experience, have completed a prior 50 mile ultramarathon, and have experience running in mountainous terrain. Self-navigation skills with map and compass are mandatory.

Runners must carry mandatory kit at all times. Required items include a full paper map for the area, a compass, a primary headtorch (minimum 75 lumens) and backup light, a thermal survival bag, waterproof jacket and trousers, warm clothing, at least 1 litre of water capacity, emergency rations, a whistle, a fully charged phone, and the supplied GPS tracker. Random kit checks take place at registration and during the event; missing kit may lead to disqualification.

Support rules restrict pacers and support runners, limit supporter access at certain checkpoints, and control parking at the start. Medals are awarded by finishing position tiers and prizes are given for top finishers. Visit the organization's website for the most recent information.
