The Karrimor Great Trail Challenge in the Lake District has opened its invitation for entries, something that may tempt many to bring their running apparel with them to Keswick in the summer.
Held on Sunday June 17th, the run starts at Fitz Park and follows the line of the former railway to Penrith, before ascending Lonscale Fell and then looping round Latrigg twice for those completing the marathon-length run.
Shorter versions will take in less of the course as runners can opt for a half-marathon or a 10k.
The race will finally finish back at Fitz Park, which lies across the River Greta from the town centre.
While many runners will enjoy a summer challenge in the Lake District, the long days of June could also be a great time to take in long walks, such as around the Skiddaw massif overlooking the town.
At 3,054 ft, Skiddaw is England's fourth highest mountain.
