Overview

Whether you’re stepping up in distance or looking for a decent challenge through wonderful countryside, both races are suitable for beginners and seasoned runners alike.

Being a bridleway the routes are well way marked, so navigation is made fairly easy (and we’ll mark any sections where you may need some help!).

The race cut-off times are 14 hours for the 50 miler and 8 hours for the Marathon, and there will be progressive cut-off times in place at various checkpoints based on the race cut-off times.

Linking with the Swan’s Way at the start, the 49 mile Three Shires Way takes in the county boundaries of Bucks, Beds and Northants at Threeshire Wood, with a 12.4 mile loop around Grafham Water to finish. We’ve added a section to the village hall at Hanslope to get to the magic 50, and created a marathon route that starts at Yelden.
