Event Overview

Midweek Chasing Numbers is a multi-distance running event held at the Wraysbury Skiff and Punting Club in Egham. This event is organized as a 7-hour Time Challenge, providing participants with the flexibility to choose their preferred distance on the day. Runners and walkers of all abilities can complete the minimum distance of 3 km to receive a finisher's medal, or continue for multiple laps to reach longer milestones.

Course Details

The route follows a signed path along a section of the River Thames. The terrain consists of approximately 60% well-made paths or tarmac, with the remaining 40% composed of grass and light trail. While road shoes are suitable throughout the year, trail shoes may be used for additional grip on the natural sections which can become muddy. The standard lap is 4.37 miles (7 km), though turn points are available for shorter distances.

Distances and Achievements

Participants can aim for various official distances based on the number of laps completed:

  • 3 km
  • 5 km
  • 10 km
  • Half Marathon (3 laps)
  • Marathon (6 laps)
  • 50 km
  • Ultra Marathon (7 or more laps)

Finishers who complete at least a half marathon receive specific distance pins to attach to their medal ribbon.

Facilities and Amenities

The race headquarters includes toilets, changing facilities, and a cafe. An unmanned bag drop is available near the start and finish line. A fully stocked aid station is positioned at the end of each lap, offering a variety of sweet and savoury snacks, fruit, and vegan-friendly options. All participants receive a goody bag upon completion, with a dedicated vegan version available. Parking is located nearby at the Runnymede Pleasure Grounds using a pay-on-exit system.
