Three Shires Way Ultra & Marathon

Hanslope, United Kingdom • 20 Jun 2026

Three Shires Way Ultra & Marathon

The Three Shires Way Ultra & Marathon offers two point-to-point trail races through rural landscapes and ancient woodlands across Buckinghamshire, Bedfordshire, and Northamptonshire. Both routes utilize the Three Shires Way bridleway, which is well waymarked for navigation.

The event features two distances:

  • 50 Mile Ultra: Starts at Hanslope Village Hall and follows the Three Shires Way, including a loop around Grafham Water.
  • Marathon: Starts at Yelden Village Hall and follows the trail to the shared finish at Marlow Park.

The courses consist of a mix of terrain, making trail shoes advisable. Both races conclude with a 12.4 mile loop around Grafham Water before finishing at Marlow Park. Because the races are point-to-point, the organizer provides a coach service from the finish line to the respective start locations for a fee.

Safety measures include professional first aid personnel and aid stations provided by volunteers offering hydration and nutrition. Participants must carry mandatory kit, including a mobile phone, a water bottle or bladder with at least 1 litre capacity, a survival blanket, and a whistle. The 50 mile race requires additional equipment such as a headtorch, hat, and gloves. Both events are cupless, requiring runners to bring their own drinking vessels. All finishers receive a medal, and digital race photographs are provided after the event. Visit the organization's website for the most recent information.
