The Machen Trail Half Marathon & Marathon are trail races near Machen, South Wales, covering approximately 14 and 26 miles respectively. The courses traverse woodland, common land, open moorland, streams, ridgeway paths, steep ascents, and fast descents, offering a challenging off-road experience distinct from road races. The half marathon course is fully marked, whereas marathon participants are responsible for navigation, with marshals present at key intersections. All participants must pass a mandatory kit check at registration; those without the required equipment will not be permitted to start. The half marathon begins in Machen, proceeding through single-track trails to Rudry Common, then into Caerphilly Forest before descending to Cefn Onn. A sustained climb leads runners back to the ridgeway, passing the Lisvane / Llysfaen trig point. The route continues through woodland towards Ruperra Castle, descends into Draethen, climbs into Machen Woods, and concludes on a downhill trail. Marathon runners cover this route and then face a significant climb towards the Rhymney Valley and the summit of Machen. This event is suited for trail runners who appreciate technical woodland paths, exposed ridges, winter kit requirements, and climbs that make the descents rewarding. Medals are awarded to all finishers, with trophies for top performers.
