BIDEFORD AAC achieved a 1-2-3 at the Arlington Court Canter 10k.
Mark Jenkin, Chris Stone and Martin Colwill led the Blues to the top three places in the 17th staging of the multi-terrain event.
In his first race since the Boston Marathon, Jenkin finished more than three minutes clear of the field with a winning time of 36mins 4secs.
The chase for second was much closer with Stone taking the honours after a fascinating three-way battle.
Colwill and Stuart Creech, of Minehead Running Club, took turns to lead the pace over the testing hills around the National Trust grounds.
While they pushed each other to the limit, Stone made his move at the right time, finishing 12 seconds clear of Colwill in 39-13.
Continuing his fine form this season, it was the first time Stone had beaten the 40-minute barrier at Arlington for several years.
The testing terrain was perfect for Jenny Horne, who returned to North Devon to take the women's title for Sheffield Running Club. Known for her strength off-road, Horne, originally from Braunton, finished in 45-54 – 24 seconds clear of Vicky Skelton.
North Devon Road Runners, the host club, took three of the top five places in women's race with Skelton followed by Alicia Leal in third and Sarah Francis fifth.
After the strong wind of last year, conditions were perfect for the 158 athletes who took part.
On Sunday, the Road Runners host the inaugural Hartland Hartbreaker.
