The event has bounced back from its enforced cancellation in 2020, returning with a new race headquarters at the Princetown Community Centre, where the organisers have been able to offer runners an improved experience and better facilities.
Hayes said: “I’m deeply grateful to the Princetown Community Centre team for their support as we worked together to stage the event. The DD is a race that has community at its heart and it’s very fitting that this fine community centre is now our new race headquarters.”
The Dartmoor Discovery, which starts and finishes in Princetown and takes runners through Dartmeet, Poundsgate, Newbridge, Ashburton, Buckland-in-the-Moor, Widecombe-in-the-Moor and Postbridge, is organised by leading South West running club the Teignbridge Trotters.

Saturday was a bittersweet day for Hayes, who was presiding over his 10th and final DD as race director.
“There has been a lot of blood, sweat and tears out on that course but there has been an incredible amount of camaraderie, support and love, too.
“I shall miss it tremendously but I know that my successor Liz Barnett will do a wonderful job of ensuring the DD continues to go from strength to strength.”
