SATURN - Midweek Chasing Numbers May 2026

This is a 7 hour timed running event held at Wraysbury Skiff & Punting Club, Egham, TW20 0AE, on a looped course along a stretch of the River Thames. The course is fully signed, mainly on well made paths and tarmac with a very short grass section; road shoes are suitable year round. The regular course may be adjusted close to the event subject to health and safety review and land owner approval.

The event uses lap-based timing so participants control their own distance within a single timed window. There are 3k and 5k turn points on the loop to allow compliance with UK Athletics distance rules for younger runners. Aid and drinks tables are available at the start/finish of each lap with a selection of savoury, sweet, fruit, cheese and vegan items. Toilets and changing facilities are at the race HQ, which also includes a café. A bag drop is provided but is unmanned; items are left at participants own risk. Headphones are permitted. Parking is available at the Runnymede Pleasure Grounds pay on exit car park near the start.

Transfer and deferral rules apply. Age restrictions apply for longer distances; minimum age is 12 years. Maximum entrants 300. Visit the organization's website for the most recent information.
