Scheduled for Friday, September 12, 2025, Midweek Chasing Numbers invites runners and walkers to set their own challenge on a scenic Thames-side loop in Egham, Surrey. Organized by Saturn Running, the event offers complete pacing flexibility—from beginners to ultramarathoners—within a 7-hour time window, beginning at 08:30 AM and closing at 15:30 PM. A full loop measures 4.37 miles (~7 km) and is fully signed, mostly paved with some grassy trail (approx. 60% path/tarmac). Participants may earn themed finishers’ medals for at least one lap, plus distance pins for half marathon (3 laps), marathon (6), or ultra distances (7+ laps) including 50 km. The event includes aid stations each lap, vegan-friendly goody bags, toilets, bag drop, and parking. Membership gives access to reduced entry prices and a guaranteed spot. With affordable costs and a welcoming atmosphere, Midweek Chasing Numbers is ideal for runners chasing numbers, PRs, or simply building mileage midweek.
