DD is the UK's longest single lap road ultra marathon, and has gained something of a cult status on the running circuit. You'll experience everything Dartmoor can offer: stunning views, beautiful scenery, wild ponies, unpredictable weather and, of course, those infamous hills! Make no mistake, this is not easy. Start the weekend off at the Friday night pasta party, then, once the small matter of 32 tough miles are out of the way, it's time to party the night away with the legendary DD disco. A weekend not to be missed! Starts and finishes in Princetown.
