Road cycling

Prepare for a challenging road cycling adventure on the Devil's Elbow loop from Brecon. This difficult 45.0-mile (72.4 km) route takes you through the stunning Bannau Brycheiniog National Park, offering 3716 feet (1133 metres) of elevation gain over approximately 4 hours and 1 minute. You will experience demanding climbs, sweeping views of the Welsh countryside, and a sense of isolated wilderness as you cycle past sprawling pastureland and rugged peaks.

Before you head out, be aware that you might encounter varied road conditions, including sections with crumbling surfaces or uneven tarmac. There are also cattle grids along the route, so stay alert. Strong winds can add to the challenge due to the exposed nature of the roads, so checking the weather forecast for the Brecon Beacons is a good idea before you start your ride.

This route is known for its blend of natural beauty and historical intrigue. As you cycle, you will pass the ancient Maen Llia Standing Stone, a landmark that has stood for 4,000 years, adding a unique historical dimension to your ride. The panoramic views on the descent are particularly rewarding, making the effort of the climbs well worth it.

Mynydd Illtud Common

Highlight (Segment) • Trail

An undulating area of common land. It's a gentle climb from the Brecon side perfect for shaking off any cafe legs. The road is quite exposed so it can be a struggle if the wind is against you. A great warm-up if carrying on to climb The Devil's Elbow.

Devil's Elbow Climb from Heol Senni

Highlight (Segment) • Viewpoint

The Devil’s Elbow epitomises the harsh beauty of hidden Wales. With its crumbling surface and neglected rusting barriers it weaves through beautifully rugged scenery presenting one of the toughest challenges of the event.

To start, leave the small village of Heol Senni, follow the river south, and begin the climb adjacent to a right-hand junction. The narrow strip of tarmac climbs and winds through twisted trees either side, easing a pinch as you cross the first of two cattle grids.

You feel like you’re in a truly isolated wilderness here as the road gradually climbs steeper up to two wicked hairpins: first sharp left and then sharp right, with a remorseless stretch in between them. Round the second hairpin and it eases to finish at the brow where the beauty of your surroundings will soon sooth any pain.

Maen Llia Standing Stone

Highlight • Monument

According to legend, the stone goes down to the river, the Afon Llia to drink on occasion. This tall tale seems likely to be an allusion to the fact that its shadow is cast across the moorland as far as the river when the sun is low in the evening sky.
