21st September 2025
Our annual Ouse Valley Way Marathon and Half Marathon 2025.
Through the county of Huntingdonshire, the Ouse Valley is 26.2 miles long and we have created a scenic route from Earith to Eynesbury, running along and near to the river. This flat route is a mix of grass, gravel and tarmac paths.
For 2025, we are switching the course and starting in Eynesbury and finishing in Earith.
