This 20km route tracks the entire length of the reservoir from the Klaus Dam to Kniewas passing by Elisabethsee. Unlike a flat lake circuit, this route is a relentless sequence of short, punchy climbs and descents, demanding high concentration and agile footwork. Typically clocked from the northern end of the Klaus Dam (Staumauer). The path consists of narrow single trails around the Klauser Stausee.

This route is designed to mimic the creation of Stonehenge. From the Blue Stones in the Preseli hills to the Sarcen stone in West Wood to Stonehenge itself.. The start point of the Waun Mawn standing stones isn't signed but very obvious when you see it. It takes in costal - mountain - rolling countryside and woodland. It incorporates, Waun Mawn, Avebury as well as Stonehenge which are internationally siginficant stone circles, all part of ancient British history and (apart from Waun Mawn) English Heritage sites.

History of the Four Meres

Standing on the western side of the Pennine watershed, the Civil Parish of Saddleworth belongs to the historic West Riding of Yorkshire.

In the Domesday Book of 1086, Saddleworth was referred to as ‘The Land of The King in Yorkshire’ and following the Norman Conquest it became a part of the Honour of Pontefract. It was then divided into four distinct quarters or ‘Meres’: Friarmere, Shawmere, Lordsmere and Quickmere.

Confusingly, the whole district was also once known simply as ‘Quick’.
