It’s all about maximum fun and minimum time. Local expert Tim Williams teaches you the tricks you need to master Cwmcarn's Twrch Trail

Cwmcarn in South Wales is one of the original trail centres, and the Twrch trail has evolved over the past decade into a true mountain bike challenge. A combination of old-school trail-building techniques and years of abuse by wind and rubber lend many sections a less man-made feel than you’ll find at other trail centres — and suspension specialists Mojo, home to this month’s expert Tim Williams, couldn’t be better placed for a demanding test track.
The Twrch is on the whole a one-line affair, with only a few subtle choices to be made on certain sections. Mastering the trail is all about technique over tricky rocks and roots, rhythm and commitment through flowing turns and, if a fast time is your aim, the fitness required to pedal hard on the climbs.
