The tough six-mile-plus fell race takes runners out of Meavy Village to Burrator Reservoir and then straight up the summit of Sheeps Tor and Gutter Tor on Dartmoor before returning to the start.
The race has traditionally been held in hot weather conditions, but this year torrential rain and strong winds made it even tougher for runners.
However, despite the tricky conditions, the top three runners home all broke the previous course record and teenager Walker also came close to Jo Meek’s women’s course record.
Third place went to Okehampton’s Samuel Priday, who clocked 39:57.9, with Oliver Mitchell fourth in 40:58.2 and Richard Parry fifth in 41:19.8.
Tavistock AC’s under-17 athlete Walker comfortably won the women’s race, coming home in a quick 44:38.3 minutes, which was the second fastest time run by a female on the course and only 47 seconds off Great Britain trail international Meek’s record.
Second woman was Claire Fraser in 47.52 minutes, with South West Road Runners’ Lucy Walker third in 48.05, Tavistock Run Project’s Rachael Malthouse fourth in 48:42.6 and Tavistock AC’s Hannah Worth fifth in 50:31.6.
Before the main race there were also junior races. Aiden Spinney won the U15 boys’ race, with Eldon Young taking victory in the U13 event, Oscar Hulbert triumphing in the U11 category and Alistair Taylor claiming the U9 honours.
Jessica Helson was the U15 girls’ winner, with Kiera Spinney taking the U13 title, Margot Goodspeed the U11 race and Lily Potter triumphing at U9 level.
