Three Shires Way Ultra & Marathon

Hanslope, United Kingdom • 20 Jun 2026

Three Shires Way Ultra & Marathon

The event offers two organised footraces along sections of the Three Shires Way through the rural landscapes and ancient woodlands of Buckinghamshire, Bedfordshire and Northamptonshire. Distances available:

  • 50 Mile Ultra, point-to-point via the Three Shires Way with a loop around Grafham Water
  • Marathon, route starting at Yelden with a finish at Marlow Park, Grafham Water

Both courses follow bridleways and are waymarked, with a 12.4 mile loop around Grafham Water included in the longer route. The 50 Mile Ultra includes an added section to reach the full 50 miles. Both races are licensed by the TRA and will be held under UKA rules. Minimum ages are 20 years for the 50 Mile Ultra and 18 years for the Marathon. Cut-off times are 14 hours for the 50 Mile Ultra and 8 hours for the Marathon; progressive cut-offs apply at checkpoints.

The races are point-to-point with coach transfers offered from the finish to the start locations for a fee. Reduced-price parking is available at the finish for runners. No pacers are permitted. Professional first aid will be available at the start and finish and race volunteers will staff hydration and nutrition checkpoints on course.

Trail shoes are advised. Mandatory kit includes a charged mobile phone with race contacts, at least 1 litre water capacity, survival blanket and whistle; races are cupless so entrants must bring their own cup. Additional mandatory items apply to the 50 Mile Ultra, including a long-sleeved top, reflective clothing, hat and gloves, and a headtorch. Prizes are awarded to the top three male and female finishers in each race and all finishers receive a commissioned event medal. Free digital race photos will be available after the event. The event supports local foodbanks and entrants will be offered an opportunity to donate. Visit the organization's website for the most recent information.
