The 17 mile course includes 6,500ft of climbing, with some of the route on the highest mountain in England, Scafell Pike, and tough climbs on Great Gable and Dale Head in the second half of the race.
Torrential overnight rain made the course wet and slippery underfoot and though the rain held off for the duration of the race, mist descended on Great Gable causing navigation problems for a large number of the field of close to 500.
Race winner was Simon Booth from the local Borrowdale club in a time of 2.49.50, while among the Calder Valley contingent were notable performances from Karl Gray, back after a short injury lay-off, who finish a creditable 11th in 3.06.06, Adam Breaks, 25th in 3.17.26 and Shaun Godsman who finished 29th in 3.22.28.
The consistent Helen Fines was sixth lady and 99th overall in 3.43.21.
Stainland Lions duo Helen Lambert and Linda Murgatroyd also took part, Lambert putting in an excellent performance to complete in four hours, 48 minutes with Murgatroyd unfortunately among those who lost their way on Great Gable and were sadly timed out.
The last race in the series will be held at Dufton in the former county of Westmorland at the end of August, where Calder Valley ladies team ae hopeful of clinching first place in the series.
