Rasus y Bannau

Rasus y Bannau comprises three long mountain races that follow a circular route around the Bannau Brycheiniog (Brecon Beacons) National Park, starting and finishing in Brecon. The event is organised by Run Walk Crawl and takes place over 2 to 3 April 2027. Minimum age is 18 years. Entry fees are listed as £99 for the 100 km, £75 for the 40 mile Ultra Trail, and £50 for the Marathon.

All races begin in Brecon town centre and climb onto the north ridge of Cribyn, then head east to Fan y Big and along the ridgeline to Carn Pica. The Marathon and 40 mile routes turn towards Blaen y Glyn and Torpantau. The 100 km route descends to Talybont Reservoir, climbs Tor y Foel, passes through the Blaen y Glyn waterfall complex and ascends Craig y Fan Ddu. From Torpantau the courses pass through Taf Fechan Forest, cross the old dam, climb Cefn Cul and Craig Gwaun Taf, and descend to Pont ar Daf. The Marathon then climbs to Corn Du and Pen y Fan before descending into Brecon. Both ultra routes traverse Fan Fawr and Fan Llia and drop to Blaen Llia; the 40 mile route continues north to Craig Cerrig Gleisiad, while the 100 km pushes west into the Black Mountain and tops Fan Brycheiniog before rejoining the 40 mile line above Craig Cerrig Gleisiad and returning via Pen y Fan to Brecon.

Race services include finishers medals, emergency first aid, GPS tracking, electronic timing, checkpoints with refreshments, route marking, mountain safety teams, a GPS file, free race photography, and one drop bag for the 100 km at the 40 mile checkpoint.
