A good pit-stop when you are out riding with an old guy called Peter James. Sometimes he'll get the cakes in!

Came here in the worst conditions. It's a rolling road so can be a bit exhausting, and if it's windy the north end is very exposed to westerlies. There's a military inn, some toilets at Epynt welcome centre and a shelter at the top of the hill if it's any bleaker than what I went through. Can imagine it's proper good on a road bike.

Confronting the Devil's Staircase northbound from near Llyn Brianne reservoir is tackling one of Wales's most infamous climbs, famed for its savage steepness and remote beauty. Prepare for an immediate, brutal ascent as the narrow single-track road rears up, averaging a punishing 10-13% but hitting steep ramps well over 20%, reportedly reaching 25-30%. Feel the wild exposure of the Cambrian Mountains, with stunningly remote views as your reward for conquering this truly devilish challenge.

A great stretch of isolated road with good views out towards the Brecon Beacons. Some stiff climbs getting to here, but the isolation and views are well worth it.

On the road from Llanerchindda to Cynghordy in the distance looms this fantastic Viaduct. It was totally unexpected find on my ride. The road takes you under the Viaduct, where there are various plaques. The Cynghordy viaduct, with eighteen arches built in sandstone and lined with brick, is 259 m (850 ft) long on a gentle curve, rising to a height of 31 m (102 ft) above the valley. It is a fine sight. Still in use today as part of the Central Wales Line.
