A multi-day mountain stage race crossing Wales north-to-south over around 386 km (240 miles) with approximately 13,000 m of ascent. The route follows the mountainous spine of Wales and includes extended sections of rough trail and open mountain terrain, with long days and cumulative elevation being the defining feature rather than single climbs. The organiser’s pack and stage information should be used for exact format, daily distances, support arrangements and navigation requirements.
