Event Overview

This event is part of Saturn Running's midweek series, designed to be affordable for runners aiming to build their event numbers or achieve personal goals. It takes place at the Wraysbury Skiff and Punting Club in Egham, next to a stretch of the River Thames.

Course

The course follows the River Thames and is fully signed. It is a mixture of surfaces: approximately 60% is on a well-made path or tarmac, with the remainder being grass and light trail that can get muddy. Road shoes are usable year-round, but trail shoes are an option. The exact loop distance may vary, but a full lap is described as 4.37 miles (7km).
