This difficult trail, estimated to take 6 hours and 49 minutes, offers expansive landscapes and rolling hills, often called the "desert of Wales." You will navigate a mix of top-quality gravel tracks, rocky singletrack, and ancient ridge roads, with the serene Teifi Pools and the impressive Claerwen Dam in the Elan Valley as notable landmarks along the way.

While many of the gravel roads are rocky and can be ridden year-round, the best seasons are generally spring, summer, and early autumn. During these times, you'll experience more favorable weather conditions, clearer views, and easier navigation. Winter can be challenging due to colder temperatures and potentially harsher conditions in the exposed uplands.
