Lord Hereford's Knob (Twmpa) trail running loop

The trail is easily accessible from the Hay Bluff car park or Gospel Pass, both of which are common starting points for routes in this area of Bannau Brycheiniog (Brecon Beacons) National Park.

The trail primarily consists of natural, well-worn pathways, suitable for trail running. You'll encounter heather-covered moorland and rocky outcrops. Be prepared for a fairly steep and grassy ascent to the summit of Twmpa (Lord Hereford’s Knob). Some sections, especially the descent from Twmpa and parts leading to a country road, can be boggy, particularly in damp conditions. Proper footwear with good grip is essential.

The trail offers stunning views year-round, but the best time for trail running is typically from late spring to early autumn. During these months, conditions are generally drier, reducing the likelihood of boggy sections. Winter conditions, including strong winds and potential snow, can significantly increase the difficulty due to the exposed nature of the hills.

Yes, the trail is dog-friendly. However, as you'll be running through open moorland where wild ponies and livestock graze, it's crucial to keep your dog under close control, preferably on a lead, to protect the animals and comply with local regulations.

The trail offers breathtaking panoramic views. From the summit of Twmpa (Lord Hereford’s Knob), you can see across the Welsh and English countryside, including distant peaks like Pen-Y-Fan. You'll also pass near Rhos Dirion summit and the Grwyne Fawr Reservoir. Wild ponies are a common sight on the grassy slopes, adding to the scenic charm.

The initial ascent to the summit of Lord Hereford's Knob is generally considered the most strenuous part, being quite steep and grassy. After this, the path can be 'easier on the knees' before another climb towards Hay Bluff. Be aware that some sections, particularly descents and parts leading to country roads, can become very boggy in wet weather. The exposed nature of the hills also means you should be prepared for strong winds and rapidly changing weather conditions.

Yes, the route incorporates sections of several other paths. You will find yourself on parts of the Cambrian Way, EuroVelo 2 - Capitals Route - part United Kingdom 2, and National Cycle Network Route 42 during this loop.

Given the varied terrain and potential for boggy sections, proper trail running shoes with good grip are essential. Due to the exposed nature of the hills, even on a clear day, it's wise to carry layers of clothing, waterproofs, and a hat. Navigation tools (like the komoot app) are recommended, especially in poor visibility, as well as sufficient water and snacks.

While generally rated as 'difficult' for jogging, the loop presents a good challenge for those with average physical fitness. The initial steep climb up Lord Hereford's Knob is the most strenuous part. If you're a beginner, be prepared for significant ascents and potentially boggy, uneven terrain. It's a rewarding route, but perhaps not ideal for your very first trail run unless you're confident in your fitness.
