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.

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.

Bwlch Bryn-Rhudd

Highlight (Segment) • Mountain Pass

The early slopes are very shallow as you pass from one village to another all the way to Glyntawe where the scenery begins to open up and the routes merge. Passing the turn to Trescastle you continue on the A4067 to traverse the Fforest Fwar, the slope now noticeably increasing in pitch.

On the smooth wide road you inch up between the high valley sides that funnel you towards the summit and once you’re pedalling comfortably you should be able to maintain a similar speed all the way to the end. As the road sweeps round to the right you’ll notice the slight V cut in the horizon ahead, this is your goal and is reached after a couple of slight kinks in direction and an ever so slightly tougher finale
