Saturn Running - Midweek Chasing Numbers

Saturn Running's Midweek Chasing Numbers event in February 2026 takes place at The Last Hop, Thames Edge Court, Clarence Street, Staines, TW18 4SU, along a stretch of the River Thames. It’s a seven-hour time-challenge where you choose your distance: a minimum 3km lap, with a full lap around 7km that may be adjusted to a 3.28-mile loop depending on course conditions. Runners may complete as many laps as they wish, with UK Athletics age rules.

Distances include half-marathon (3 laps), marathon (6 laps), 7+ ultramarathon, and a 50km option. The course is signposted on paths and tarmac; medals, distance pins, and vegan goody bags are included. Visit the organization's website for the most recent information.
