Chatsworth Challenge 25m Paul Burgess reports: The Chatsworth Challenge is a fantastic event for both runners and walkers, and covers 25 miles and 3500 feet of beautiful Peak District countryside. The race starts with a steep climb onto Baslow Edge, with spectacular views of the cliffs, and continues along the top of Curbar Edge, before dropping down into the Derwent Valley. There's then a succession of hills to climb, moors to cross, and valleys to admire, before the course finally flattens out for the finish through the grounds of Chatsworth House. To complete a perfect day, there's free pie, peas, gravy, tea and as much cake as you can eat in the village hall afterwards. Event rating : 11 / 11.
