The Beacons Way Ultra 100km is a 62 mile (100 km) ultramarathon across the Brecon Beacons National Park on Saturday 25 July 2026. The route follows the official Beacons Way trail, starting near Talybont and crossing notable high ground including Pen-y-Fan and the Carmarthen Fans, with a total ascent of 3178 m. The event has 250 places and a 24 hour overall cut off. The published entry fee is £119.

The race is self-navigation and requires map and compass competence. Six staffed checkpoints are provided along the route offering drinks, snack food, vegetarian and vegan options, hot food at indoor stops where available, and medical or first responder cover.

The 100 km event carries UTMB and ITRA points and is a Western States 2027 qualifying race for runners who complete within 21 hours.

Mandatory kit must be carried at all times and includes a hardcopy topographic map, a compass, a charged phone, a GPS tracker provided at registration, a headtorch and backup light, waterproofs, warm layers, a thermal survival bag, emergency food and at least 1 litre of water.
