Beacons 50 & Beacons 100 2026

In the Brecon Beacons National Park, including Black Mountain, the Beacons 50 & Beacons 100 are mountain trail races you mark in your calendar because they will properly test you. The source describes it as an “authentic setting in the heart of Wales,” and that fits: high ground, long hours, and no unnecessary embellishment. The 2021 results already suggest a difficult day, with small fields and many participants not finishing. Expect mountain running, not a simple tour: trail underfoot, significant climbing, and terrain where pacing is more important than bravado. The longer race had only a few recorded finishers in 2021, with the leaders still out for almost a full day. The participants are likely runners who understand patience, weather, and navigating difficult terrain. The appeal is straightforward: Brecon Beacons, Black Mountain, and a finish that is earned.
