The 20-year-old, who had been training for the event for six months, took victory in the 32-mile challenge in an impressive time of three hours, 44 minutes and 50 seconds.
He won by race, which is the UK’s longest single lap road ultra marathon and takes competitors up and down some of the toughest hills Dartmoor has to offer, by nine minutes.
Afterwards Beaton said: “Winning this brutal historic race was a dream of mine. Over the moon with the finishing time and I will definitely be back in the future.”
Second woman home and first F45 was Looe’s Joanne Robinson, who clocked 4:43.44, with Westbury’s Hannah Large third in 4:47.14.
The race, which is now organised by Teignbridge Trotters, saw 149 finishers.
If running 32 miles along some of the hilliest roads in Devon in hot conditions was not tough enough, runners have to meet strict cut-off times along the way and finish in under six-and-a-half hours.
