Black Beacon Mountain Trail Races

Black Beacon Mountain Races are a linear, long‑distance mountain trail event crossing the Black Mountains and Bannau Brycheiniog (Brecon Beacons) National Parks from south to north in Wales. Four distances are offered: Black Beacon 100 (100 miles, +7500m), Black Beacon 50 (50 miles, +3750m), Ultra Bach (50 km, +2200m), and the Trail Race (21 miles, +1200m). The routes run from Hay-on-Wye to Pontneddfechan (and back for the 100) through waterfall country and high ridges, with 44 summits on the 100‑mile course.

The trails are fast and not overly technical, with relatively straightforward navigation and spectacular scenery. Supported by volunteers and staff, with multiple checkpoints and safety coverage; GPS maps and tracking are provided. Visit the organization's website for the most recent information.
