50 Mile Ultra and Marathon distance races through the quiet rural landscapes and ancient woodlands of Bucks, Beds and Northants along the Three Shires Way.
As with all Race Harborough events, there will be professional first aid on hand at the start and finish with the ability to access runners on the course. Race Harborough volunteers will also be on-course to provide hydration and nutrition at a number of checkpoints/aid stations on the routes.
No pacers are permitted in either race. Entries, and transfer of entries, will close 7-days before the event.
Monthly averages based on historical data (2000–present).
