Now in its 5th year... From a grand setting high above the steep Teign Valley, on the northern fringes of Dartmoor, this is PureTrail’s first foray into the Big Woods of Fingle. A tough half marathon and a 10k race both start and finish at the iconic Castle Drogo on Dartmoor. The trails go deep and steep, down to the depths of the Teign River Valley, then rising above the Fingle treeline. Two extremely tough races in the most wonderful woodland.
