Saturn Running - Have You Ever Seen A Nessie in The Thames Charity Run

This is a charity Time Challenge event held by Saturn Running along a stretch of the River Thames in Staines. The event raises money for The Mental Health Foundation through a mandatory surcharge and optional donations that are matched by the organiser. A compulsory £2 surcharge on every race entry is donated in full to the charity. An optional £3 donation adds a mini Nessie pin and is matched by Saturn so local rehoming centres receive £6 for each pin option selected. Ten percent of race profits are also donated.

The event runs as a seven hour Time Challenge with flexible distances. The minimum recorded distance is 3 km and a full lap is listed as 7 km (4.37 miles) though the loop length may change. Turn points at 3 km and 5 km are provided to meet UK Athletics age rules.

The course follows mainly well made paths and tarmac with a short grass section, is fully signed, and is suitable for road shoes.

There is an aid table with drinks and snacks at the start and finish area. Toilets are available on site. A bag drop is provided but is not secure.
