Event overview
The route takes in areas of the Afan Forest and Rhigos mountain range, and finishes along the popular sections of the incredible high-level trail, the 'Coed Morgannwg Way'. On your journey through ancient woodlands you will pass hidden reservoirs, towering wind turbines and unrivalled views of the Brecon Beacons National Park. The route culminates in a dramatic, fast descent into a lively and festive finish at Dare Valley Country Park. The dramatic, rugged routes follow ancient tracks of Celtic origin, with amazing views across the Brecon Beacons, Black Mountain, South Wales Valleys and South Wales Coast. The route mainly follows wide forest tracks on some of South Wales' most hidden trails. There are sharp climbs, long fast descents, river crossings and sections of single track all with a wild and remote feel. The paths here, while fast and runnable, feel a little less travelled. There are 3 race distances to choose from all of which finish at the beautiful Dare Valley Country Park. The Celtic Ultra is a circular route starting and finishing in Dare Valley Park - 34 miles - 5850 ft ascent. The Celtic Trail Marathon is a circular route starting and finishing at Dare Valley Country park. 26 miles - 4200 ft ascent. The Celtic Trail Half Marathon is a linear route starting at Resolven - 13 miles - 2200 ft ascent. All courses are FULLY MARKED.
