Three Shires Way Ultra & Marathon

The event offers two point-to-point races along the Three Shires Way through rural landscapes and ancient woodlands in Buckinghamshire, Bedfordshire and Northamptonshire. Distances on offer are:

  • 50 Mile Ultra
  • Marathon

Both races are licensed by the TRA and held under UKA rules. The 50 mile event follows the 49 mile Three Shires Way with an added section to reach 50 miles; the finish includes a 12.4 mile loop around Grafham Water. GPX route files are provided for both distances. Minimum age on race day is 20 for the 50 mile race and 18 for the marathon. Race cut-off times are 14 hours for the 50 mile and 8 hours for the marathon, with progressive checkpoint cut-offs; no pacers are permitted. Entries and transfers close seven days before the event. Entry prices are listed at £70 for the 50 mile and £40 for the marathon; a coach service from the finish to the start is available for a fee of £14 and parking at the finish is offered at a reduced price of £5 for the day.

On-course support includes professional first aid at start and finish and volunteers at aid stations. Mandatory kit includes a charged mobile phone, at least 1 litre water capacity, survival blanket, whistle, and a personal cup; additional items are required for the 50 mile field. Prizes are awarded to the top three male and female finishers and all finishers receive an event medal. Free digital race photographs are made available after the event. The event supports local foodbanks and offers entrants the opportunity to donate to those charities. Visit the organization's website for the most recent information.
