Lovely smooth flowing single-track with plenty of berms and rollers. Nothing too taxing, a trail for most beginners to build some confidence.

The original Redbull trail where it all started. Rocky with some really great technical sections

A long section of singletrack trail on the Dragon's Back & Beast trails. It climbs, contours and descends with fast & flowy and some surprising techy sections, both up and down. Riding through the huge, mature Douglas Firs, you can be forgiven for thinking that you're riding through the Canadian wilderness. This is a classic Coed y Brenin section of trail. If combined with 'Pink Heifer' it's over 4km of singletrack. Quite possibly, the longest section of purpose built, singletrack trail in the UK. Probably! :)

by far the best track at Codey Brennin, fast, steep and swoopy, relatively smooth compared to other tracks here. some tough technical climbs mid section and some heavily rooted downhill sections, a good dropper and decent suspension is a must .
