2018 sees the DD celebrate its 20th anniversary, for one year only the course will revert back to its original distance of 34 miles.
The Dartmoor Discovery, or DD as it's affectionately known, is the UK's longest single lap road ultra marathon.
It has gained somewhat of a cult status on the running circuit and is one of those races that runners have to have on their CV.
The race starts and finishes in Princetown. The 34-mile course takes you up and down some of the toughest hills that Dartmoor has to offer. There are 11 feeding stations on route, ten of which you can leave your own personal drinks at. A bespoke quality DD medal awaits anyone crossing the finish line in under the 6 hours 50 minutes cut off time.
The DD weekend finishes with the legendary DD disco on the Saturday night.
