The Sloth Scamper - Staines upon Thames

Organised by Saturn Running at The Last Hop, Thames Edge Court, Staines, TW18 4SU on 14 March 2026, this event is presented as a seven hour Time Challenge that lets participants choose their own distance within the event window. A minimum distance of 3km counts as an official finish.

The course runs along a stretch of the River Thames, is fully signed, and uses mainly well made paths and tarmac with a short grass section. Road shoes are suitable year round. The lap is listed as 4.37 miles (7km) but may change to a 3.28 mile loop depending on course conditions. There are 3km and 5km turn points on the lap to support age-restricted distances under UK Athletics rules.

Finishers who complete at least 3km receive a sloth medal. Distance pins are issued for half-marathon and longer finishes, including Half-Marathon, Mega-Half, Marathon, 50km and Ultra pins. A goody bag is provided to finishers, with a vegan goody bag option available if requested at entry. An aid and drinks table with sweet and savoury snacks, including vegan options, is available at the start/finish of each lap.

Toilets and changing facilities are available at the venue HQ for the duration of the event. Parking is available at Bridge Street Car Park, Staines TW18 4TP.
