From Talgarth, the route follows country lanes to the lower slopes of the Black Mountains before a push-carry-thrutch up a well-armoured path to the top of Y Das. From there its a plummet to the shores of the Grwyne Fawr reservoir and onwwards through Mynydd Du forest. The ride then climbs on gravel fire road before spitting you out on wild moorland below Crug Mawr. Another whip-fast, swoopy descent over moorland track and woodsy switch-backs lands you in Llanbedr village.
Draw breath now before climbing back high into the guts of the Black Mountains to a broad shoulder below Pen Trumau. A final treat lies in store – a rollercoaster plummet back to base down grassy sheep track and narrow, rocky chutes.
Be aware that this is a committing route, in a remote, mountainous setting – check the weather before setting off, go properly equipped for a big a day in the hills and be prepared for some big, long climbs.
