Saturn Running - Midweek Chasing Numbers July 2026

This is a 7 hour Time Challenge event held at Wraysbury Skiff and Punting Club, Riverside, Egham TW20 0AA. Participants may choose how many laps to complete within the time limit; the minimum recorded finisher distance is 3 km. A full lap is described as 4.37 miles (approximately 7 km), though the course may be changed to a 3.28 mile loop depending on conditions. Age-based distance restrictions apply under UK Athletics rules, and the lap contains 3 km and 5 km turn points for compliance.

The course follows a stretch of the River Thames and is fully signed. Surface is approximately 60% well-made path or tarmac and the remainder grass and light trail that can become muddy. Road shoes are suitable year round; trail shoes may be preferred for extra grip. The regular course may be altered subject to health and safety reviews and landowner approval.

Finishers who complete at least 3 km receive a medal. Distance pins are awarded for Half-Marathon, Mega-Half, Marathon, 50 km and Ultra achievements and are attached to the medal ribbon. All finishers receive a goody bag; a vegan goody bag option is available. An aid table and drinks are provided at the start/finish of each lap with savoury, sweet, fruit, cheese and vegan items.

Facilities at race HQ include toilets, changing and a cafe. Bag drop is unmanned and items are left at the participant's risk. There is a large pay on exit carpark at Runnymede Pleasure Grounds. Headphones are allowed. Events take place on public footpaths so participants should be considerate of other path users.
