SATURN Eggcellent Easter Orange Run - 7 Hour Time Challenge

This event is a seven hour timed challenge held as the first day of a five day series where finishers receive an orange Easter egg themed medal and an Easter egg. It is based at Runnymede, with race HQ at Wraysbury Skiff & Punting Club, Egham (TW20 0AE).

Runners choose their distance; the minimum official finishing distance is 3 km. The usual lap is given as 4.37 miles / 7 km but may be changed to a 3.28 mile loop depending on course conditions. Within the lap there are 3 km and 5 km turn points to allow younger runners to meet UK Athletics distance rules. Typical lap counts: three laps for a half marathon, six for a marathon, seven or more for an ultra. A 50 km option is available. Minimum entry age is 12 years; anyone wishing to run over 45 km must be 20 or older.

The course follows a stretch of the River Thames and is fully signed. About 60% is on well-made path or tarmac and the remainder is grass and light trail which can be muddy at times. Road shoes are suitable year-round; trail shoes may help on wetter sections.

Facilities include toilets and changing at the HQ with a cafe, a bag drop area that is not secure, a pay-on-exit car park at Runnymede Pleasure Grounds, an aid and drinks table each lap with mixed food including vegan options, and a goody bag for finishers including a vegan goody bag choice. Distance pins are awarded for half-marathon and longer distances. Transfers and one-time deferrals are permitted under the organiser terms. Final race instructions are issued in the week before the event and race numbers are collected at registration on the day. Visit the organization's website for the most recent information.
