About The Northumbrian
Kielder Water and Forest Park

The ultimate endurance test will be open to a limited number of individuals and teams to conquer the beautiful waters, forests and terrain that give Northumberland and Kielder its unique character. The summer of 2025 will welcome the fourth edition of an event which combines scenery, fortitude, adventure, and achievement. Everything it takes to be recognised as a NORTHUMBRIAN.
