Machen Trail Races: Half and Full Marathons

The half marathon
Starting in Machen, the route winds its way through some beautiful single track trails to Rudry Common. Once over the common, a short trip into Caerphilly Forest, then over the hill and a glorious downhill belt to the Cefn Onn Checkpoint. Once through the checkpoint, a long climb back to the top of the ridgeway, passing Llysfaen Trigpoint. A very special trip through both deciduous and pinewoods leads you to Ruperra Castle. Down into Draethen, where sadly the pub is shut, and the final climb up into Machen Woods, leading to a final trail back to the start and a well earned rest. There is mud, hill tops, sea views and meandering forest trails. It is really one of the best routes out there.

Previous entrants have mentioned the race is not easy, though those that have, have said they will be back - its one of those races, that makes you feel great for having really achieved something - mainly because of the amazingly reputational support from the volunteers.

The marathon
Continuing after completing the half route there is a tough climb to the Rhymney Valley Ridgeway. Once on 'the top' there is good track running for several miles, which should warm you up! Bomb down to the right toward Wyllie, and right again onto the Sirhowy Valley Walk. A very enjoyable downhill trot on single track to the bottom. After a few tricky turns and a steep ascent back onto the ridgeway, good running again takes you to the highest point of your day, and Mynydd Machen Trig. A quad bashing decent back to Machen and the finish.

The marathon is a tough race in its own right, and is also perfect for those training for a mountain ultras
