Saturn Running - Midweek Chasing Numbers (July 2026)

Saturn Running stages a midweek Chasing Numbers event in Staines that operates as a 7 hour Time Challenge. Participants choose how many laps to run within the time limit; the minimum recorded distance is 3 km. The event is licensed by the Trail Running Association and is held under UK Athletics rules.

The course runs along a stretch of the River Thames and is fully signed. About 60% of the route is on a well-made path or tarmac, with the remainder on grass and light trail that can become muddy. Road shoes are suitable year round and trail shoes may be preferred for grip on softer sections. The regular course layout may be altered for health and safety or land owner requirements.

Finishers who complete at least one lap receive a medal. Distance pins are awarded for half-marathon distance and above; available pins include Half-Marathon, Mega-Half, Marathon, 50km and Ultra, with one pin added to the medal ribbon. An aid table and drinks table are available at the start/finish of each lap, offering savoury, sweet, fruit, cheese and vegan items. All finishers receive a goody bag, with a vegan option.

Venue facilities include toilets at The Last Hop; there are no dedicated changing rooms or showers. Parking is available at Bridge Street Car Park, Staines. Headphones are permitted. Race numbers are collected on the day at race registration and final instructions are emailed the week before the event. Visit the organization's website for the most recent information.
