The Beacons Way Ultra 100km is a 62-mile (100 km) ultramarathon across Bannau Brycheiniog, the Brecon Beacons National Park, with 3178 m of ascent following the official Beacons Way trail. The route includes the Central Fans and Pen-y-Fan (886 m) and crosses the Carmarthen Fans. The field is limited to 250 places and the event has a 24-hour overall cut-off.

The race is self-navigated and requires competence in map-and-compass navigation.

There are six staffed checkpoints on course offering drinks, hot and cold food options, vegetarian and vegan choices, and medical or first-aid cover.
