The Greenway Challenge takes in a 13.1 miles of the Garden City Greenway in a clockwise direction starting from Standalone Farm in Letchworth. The route is self-guided, you'll be given a map and instructions but you are responsible for getting yourself around the route. There will be marshals at road crossings but you are responsible for your own safety.
