Beacons Way Ultra 100km

The Beacons Way Ultra 100km is a 100 kilometre (62 mile) ultramarathon across Bannau Brycheiniog, the Brecon Beacons National Park, with 3178 m of ascent. The route follows the official Beacons Way trail, passing the Central Fans including Pen-y-Fan (886 m) and the Carmarthen Fans. The event offers UTMB Performance Index and ITRA points and is a Western States 2028 qualifying race for runners who meet the stated qualification condition.

The race has capacity for 250 places and a 24 hour overall cut off. There are six staffed checkpoints on course providing drinks, snacks, vegetarian and vegan options, hot food at indoor locations and basic medical cover. Checkpoints enforce cut-off times and require every participant to check in; failure to do so leads to withdrawal.

Entrants must be at least 20 years old and declare suitable experience. Required experience includes successful completion of a 50 mile ultramarathon and competence in map and compass navigation for mountainous terrain. Pacers or unregistered support runners are not permitted.

Mandatory kit must be carried at all times and is checked at registration and randomly during the race. Key items include a full paper map for the area, compass, GPS tracker, headtorch and backup light, warm and waterproof clothing, water container and emergency rations. Two small dropbags may be used subject to size and weight limits. Optional coach return transport and prebooked parking on a designated field are available for participants.
