About the race

The Three Shires Way Ultra & Marathon are point-to-point trail races that follow the Three Shires Way through Buckinghamshire, Bedfordshire and Northamptonshire. The routes run along bridleways and ancient woodlands, include a loop around Grafham Water, and finish at Marlow Park, Grafham Water. GPX files are available for both routes.
