Three Shires Way Ultra & Marathon

The event offers two point to point running distances along the Three Shires Way through rural landscapes and ancient woodlands in Buckinghamshire, Bedfordshire and Northamptonshire, finishing with a loop around Grafham Water.

Distances

  • 50 Mile Ultra
  • Marathon

Both races are licensed by the Trail Running Association and will be held under UK Athletics rules. Routes follow bridleways and are waymarked; organisers will mark sections where extra navigation help is needed. GPX files are provided for both routes. Tracking and timing are supplied; participants receive a tracker at registration and must return it at the finish. The race is cupless so participants must bring their own cup.

Mandatory requirements include a fully charged mobile phone with race emergency numbers, a water bottle or bladder holding at least 1 litre, a survival blanket, a whistle, and for the 50 mile event a long sleeved base layer or fleece and reflective top or bands. Trail shoes are recommended because terrain varies. No pacers are permitted. Cut off times are 14 hours for the 50 mile and 8 hours for the Marathon; progressive cut offs apply at checkpoints. Minimum ages are 20 for the 50 mile and 18 for the Marathon.

Support includes professional first aid at start and finish and volunteers manning aid stations. Prizes are awarded to the top three male and female finishers and all finishers receive an event medal.

Entry fees, coach transport from the finish to start locations, parking at the finish at a reduced price, race merchandise prices and charity donation opportunities are listed by the organiser. Visit the organization's website for the most recent information.
