This is the trail that everyone aspires to ride. It’s long, it’s tough, it will stretch you physically, mentally and has left many broken souls!

This long distance route covers 35 km so go prepared with adequate fluids, clothing and bike spares. Expect to come back tired, muddy and exhilarated!

You can expect loose rocky climbs, gnarly descents, stone fly-offs, berms, tabletops and hips on this 35km trail.

Don’t miss the Pink Heifer, Big Doug combo that gives over 4km of continuous sublime singletrack through majestic tall Douglas firs.

Smash it in a oner and feel the burn! So will you be dragging yourself up the final climb, limping down the last descent utterly spent or will you rise to the challenge and tame the Beast?

The Coed y Brenin mountain bike trails are managed and maintained by Natural Resources Wales. Car parking at Coed y Brenin costs £1 for 1 hour, £3 for 3 hours or £5 for the day – the money collected goes towards maintaining and improving the trails.

 The singletrack is utterly fantastic, the amount of dirt road you've gotta ride is not.

 Very little is actually black (after the first section, it's dragon's back the rest of the way), but it's definitely a workout for the hands. Great views, and the trail goes by some nice landmarks and the river. There is a lot of fireroad (I saw BKXC's video of this before going :-), but 90% of the DH is singletrack. It was pouring rain when I started the ride and it stopped about halfway through. It's amazing how well it holds up in the wet and how fast it dries out. Lots of fun and my legs found it longer than the stats suggest!

 Rode this at the weekend. It had rained all night and continued throughout the ride. The trails (and the grip) held up well despite water flowing down some sections. There's a lot of fireroad but it's worth it for some of the singletrack. You can access some of that through other trails but if you know what you're getting into (watch the @bkxc vid) then it shouldn't be a surprise. Will ride it again.
