Beacons Way Ultra 100km

The Beacons Way Ultra is a 100 km (approximately 62 miles) ultramarathon across Bannau Brycheiniog, the Brecon Beacons National Park, with 3,178 m of ascent. The route follows the official Beacons Way trail, starting near Talybont and taking in terrain including Pen-y-Fan and the Carmarthen Fans. The event is scheduled for Saturday 25th July 2026 and has 250 places with an entry fee of £119. The overall event cut-off is 24 hours.

The race is self-navigation and requires map and compass competence. Entrants must be at least 20 years old, in good health, and have previously completed a 50 mile ultramarathon and have mountain running experience. The 100 km race awards UTMB Performance Index and ITRA points and is a Western States 2027 qualifying race for runners who complete within 21 hours.

There are six staffed checkpoints offering drinks, snacks, hot food at indoor sites, vegetarian and vegan options, and on-site medical cover. Mandatory kit must be carried at all times and is checked at registration and randomly on course; key items include a full paper OS or Harvey map, compass, headtorch (min 75 lumens), backup light (min 25 lumens), mobile phone, thermal survival bag, waterproof coat and trousers, warm hat, gloves and at least 1 litre of water.
