The route is a strenuous 33 miler, starting and finishing in Haworth and passing through Hebden Bridge and Todmorden and alongside several reservoirs high up on the moors.
Race winner was Matt Giles from Stourbridge in the West Midlands in a time of 4.06.43, hotly pursued by Calder Valley runner Adam Breaks in 4.09.04.
Adam had the consolation however that his race record time of 3.43.24 from last year is still intact. The 100km World Champion Liz Hawker was first lady home in 4.36.54.
Other notable successes for Calder Valley were: 2nd team and 12th overall, Jason Stevens of Sowerby Bridge and Mytholmroyd's Richard Greenwood in 4.47.58; 1st ladies pair Thirza Hyde and Barbara Lonsdale in 6.29; 1st mixed pair Bill and Anne Johnson of Luddenden in 5.24.20.
