This route was planned by komoot.
This route is rated as difficult and is best suited for experienced joggers with good fitness levels. It involves significant steep ascents and descents, which can be very demanding. Some sections require careful footing due to rough and rocky terrain.
The terrain is varied and challenging. You'll encounter easy paths through woodlands and fields, grassy sections, and some tarmac lanes. However, as you ascend, expect steep climbs, rough ground, and rocky sections. Some flatter areas can be boggy, and paths on the horseshoe ridge can be technical and uneven.
The loop takes in four prominent peaks: Fan y Big, Cribyn, Pen y Fan, and Corn Du. You'll also find the famous 'diving board' rock at Fan y Big, a popular spot for photos. Other highlights include Craig Cwareli and the stunning views from Bwlch y Ddwyallt.
Specific parking details are not provided in the tour data, but typically, routes in the Brecon Beacons National Park (Bannau Brycheiniog) start from designated car parks. It's advisable to research local parking options near the common starting points for the Pen y Fan Horseshoe routes before your visit.
While dogs are generally welcome in Bannau Brycheiniog National Park, it's crucial to keep them on a lead, especially around livestock and ground-nesting birds. Given the challenging terrain and potential for rocky sections, ensure your dog is fit enough for the route and carry enough water for both of you.
No, there are no specific permits or entrance fees required to access the trails within Bannau Brycheiniog National Park, including the Fan y Big Horseshoe Race Skyline loop. However, parking at popular trailheads may incur a charge.
Clear days offer magnificent experiences with continuous panoramic views. However, adverse weather can make the route serious very quickly. Spring and autumn can be ideal, offering cooler temperatures and potentially clearer skies, but always check the weather forecast before heading out. Avoid winter unless you are highly experienced and equipped for snow and ice.
Given the route's difficulty and varied terrain, essential gear includes appropriate trail running shoes with good grip, waterproof and windproof layers, sufficient water and snacks, a map and compass (or GPS device) as navigational skills are required, and a fully charged phone. Visibility can drop quickly, so be prepared for changing conditions.
Yes, the route shares sections with several other notable trails. You will find parts of the Beacons Way, the Cambrian Way, Cycle across the Beacons, Lôn Las Cymru (South), and the Taff Trail along its course.
Joggers are rewarded with breathtaking and continuous panoramic views. You'll see the full horseshoe route unfold, dramatic escarpments, and a magnificent glacial landscape. On a clear day, expect incredible vistas across the Brecon Beacons, towards the Black Mountains, Carmarthenshire Fans, and even as far as the Bristol Channel.
The estimated duration for this 19 km (11.8 mile) route is approximately 2 hours and 15 minutes of active jogging time. However, this is for experienced individuals. Given the difficult terrain and significant elevation gain, allow extra time for breaks, navigation, and enjoying the views, especially if you plan to hike sections.
