The Grim Reservoir Dogs Canicross Challenge

The Grim Reservoir Dogs Canicross Challenge is a dog-friendly trail run around Fewston and Swinsty Reservoirs in North Yorkshire, offering 3.3-mile or 6.7-mile options. It is designed for people running with their dogs, though the organizers frame it as a fun dog race, not a formal canicross event. Participants can enter for one day or multiple days within the series. The setup is straightforward: off-road reservoir paths, a clearly marked route, marshals on course, and aid stations approximately every 3 miles. Both distances follow the same looped course, encircling the reservoirs on wide, maintained trails through woodland and alongside the water. The terrain consists of good-quality trail with some hills, suitable for runners and dogs accustomed to off-road running. Finishers receive a custom medal, and dogs get rewards including treats and a neckerchief. Practical arrangements include public toilets and pay-and-display parking near registration.
