Usk Reservoir running loop — Brecon Beacons National Park

Embark on the Usk Reservoir running loop, a moderate 6.1-mile (9.8 km) jogging route in Brecon Beacons National Park. You will gain about 410 feet (125 metres) in elevation, with most runners completing it in approximately 1 hour and 16 minutes. This popular trail offers picturesque views of the Usk Reservoir, winding through the tranquil Glasfynydd Forest on compacted stone forestry tracks and quiet public roads. While generally level with some short climbs, be aware that muddy puddles can form on the paths after rain, and a footbridge bypass is available at the ford on the western side.

To best enjoy your run, prepare for varied surfaces and potential mud, especially if there has been recent rainfall. The route is generally accessible, but good fitness is recommended to comfortably tackle the undulating sections. This loop is a favorite among joggers, walkers, and cyclists alike, offering a well-maintained path suitable for a steady run in a remote and peaceful setting. Consider starting your run earlier in the day to fully appreciate the expansive reservoir views and sheltered woodland sections.

What makes this trail particularly notable is its blend of accessibility and stunning natural beauty, set within the upper Usk Valley at an elevation of 1,006 feet (307 meters). As you jog, you will enjoy a circular route that fully immerses you in the reservoir and its surroundings, with glimpses of the distant Black Mountains. The remote location also makes it an excellent spot for stargazing, adding a unique dimension to your outdoor experience.
