Midweek Medal Madness - Leon's Birthday Run

The Saturn 7 Hour Time Challenge is a flexible distance event held in Staines-upon-Thames. This specific edition also serves as a birthday celebration, featuring birthday cake for participants to share. The event follows a timed format where runners have a total of seven hours to complete as many or as few laps as they choose.

The course is located along the River Thames and consists primarily of well-made paths and tarmac with a very short grass section. The route is fully signed and relatively flat, making road shoes suitable for the duration of the event. A standard lap covers 7 km (4.37 miles), though this may be adjusted to a 5.27 km (3.28 mile) loop based on ground conditions. Specific turn points are placed at 3 km and 5 km to accommodate different distance goals and age restrictions.

Available distances include:

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

Participants have access to an aid station at the start and finish of each lap, stocked with sweet and savoury items, fruit, cheese, and vegan options. All finishers who complete at least 3 km receive a themed medal and a goody bag. Specific distance pins are awarded for completing a Half Marathon or further. Facilities at the venue headquarters include toilets and changing areas, available from 8:00 am. Limited bag storage is available, though it is not a secure area. Parking is located nearby at the Bridge Street Car Park. Visit the organization's website for the most recent information.
