Prepare for a challenging jogging experience on the Mynydd Llangorse and Cwmdu Loop, a difficult 8.1 miles (13.0 km) route that climbs 1767 feet (538 metres) in elevation. You can expect to complete this circuit in about 1 hour and 42 minutes. As you ascend, the terrain shifts from easy grass tracks to sections with heather and gorse underfoot, and some rocky, uneven paths. On a clear day, the panoramic views are extensive, revealing Llangorse Lake, the Black Mountains, and the distant outline of Pen y Fan. Keep an eye out for Red Kites circling above the heather-strewn moors, adding to the wild atmosphere of the Brecon Beacons.
To begin your jogging adventure, head to the Cwmdu village hall car park, where convenient parking is available. The village of Cwmdu serves as an excellent starting point, offering amenities such as a pub and tea rooms if you wish to refuel before or after your run. Since this is a difficult route, consider starting early in the day to allow ample time and avoid the hottest parts of summer days. Always check local weather conditions before you set out, especially given the exposed nature of the higher sections. While no permits are required, ensure you are prepared for the varied terrain and elevation changes.
Mynydd Llangorse is designated as "open country," meaning you have free access to explore its expansive landscapes. This trail is particularly notable for its ever-changing vistas, which transform as you gain elevation, providing different perspectives of the surrounding national park. The presence of heather and gorse underfoot, along with the potential to spot Red Kites, highlights the unique natural environment of this part of Bannau Brycheiniog. It offers a rewarding sense of accomplishment for those seeking a strenuous jog with significant elevation gain.

The trail features varied terrain. You'll encounter mainly easy grass tracks, especially on broader ridges, but also sections with heather and gorse underfoot. Some parts can be rocky and uneven, requiring attention, particularly when wet. The route also includes quiet country lanes, some deeply rutted tracks, and sections of footpath. Overall, it's a mix of unpaved, natural, and asphalt surfaces.
While the route is generally rated as 'moderate' for hiking, the tour data classifies it as 'difficult' for jogging due to its distance and elevation gain. Some sections may present challenges with varied terrain, including rocky and uneven paths. It's best suited for joggers with a good level of fitness and sure-footedness, rather than absolute beginners.
The Mynydd Llangorse loop is renowned for its glorious and panoramic views on a clear day. From the ridges and summit, you can expect stunning vistas of Llangorse Lake (South Wales' largest natural lake), the Black Mountains, the central Brecon Beacons (including the distant outline of Pen y Fan), and the Usk Valley. You'll also see patchwork fields, neat stone walls, and heather-strewn moors. Keep an eye out for wildlife like Red Kites.
Yes, the route offers several notable points. You'll pass by the Mynydd Llangorse Trig Point and reach the Mynydd Llangorse Summit, both offering exceptional views. Part of the trail also traverses Cefn Moel, a spur of Mynydd Llangorse, which is part of the Beacons Way long-distance footpath.
Yes, the area is generally dog-friendly as Mynydd Llangorse is designated 'open country'. However, it's crucial to keep dogs on a lead, especially during lambing season or when livestock are present, and to protect local wildlife. Always follow the Countryside Code.
The trail offers beautiful scenery year-round, but for the best experience, consider visiting during late spring, summer, or early autumn. Clear days will provide the most spectacular panoramic views. Late summer is particularly lovely when the heather is in bloom across the moors.
No, there are no permits or entrance fees required to access the Mynydd Llangorse loop or to visit Bannau Brycheiniog (Brecon Beacons) National Park. The park is freely accessible to the public.
When visiting Bannau Brycheiniog National Park, please follow the Countryside Code. This includes taking all litter home, keeping dogs under control (especially near livestock), closing gates, and sticking to marked paths where appropriate. Respect the natural environment and local communities to help preserve the park's beauty.
Yes, a significant portion of the route, specifically along Cefn Moel, is traversed by the Beacons Way long-distance footpath. This means you'll share sections with hikers undertaking this longer journey.
Given the varied terrain and potential for uneven, rocky, or wet sections, sturdy trail running shoes with good grip are essential. Layers of clothing are advisable due to changing weather conditions, even on clear days. Bring enough water, snacks, a map or GPS device (like komoot), and a fully charged phone. Waterproofs are recommended regardless of the forecast.
