Saturn Running stages a 7 hour time challenge beside the River Thames from The Last Hop in Staines, giving runners control over their own distance from a minimum recorded 3 km right up to 50 km. The course is a fully signed lap, listed at 7 km (4.37 miles) but sometimes changed to a 3.28 mile circuit depending on conditions, with 3 km and 5 km turn points inside the lap to support the age-related distance rules. Roughly 60 percent of the ground is well-made path or tarmac, and the rest is grass and light trail that can turn muddy; road shoes work year round, though trail shoes are preferred for grip when it is wet. A typical half marathon is 3 laps, a marathon is 6 laps and an ultra is 7 laps or more. Finishers covering at least 3 km earn a medal, and anyone reaching half marathon distance or beyond collects a distance pin for the medal ribbon, with a goody bag including a vegan option and an aid and drinks table waiting at the start and finish of each lap. The event is licensed by the Trail Running Association and held under UK Athletics rules, with number pick up on the day and final instructions emailed in the week before.
