Three Shires Way Ultra & Marathon

The event takes place on Saturday 19 June 2027 and offers two distances that run along the Three Shires Way through Buckinghamshire, Bedfordshire and Northamptonshire.

Distances

  • 50 mile Ultra
  • Marathon

Both routes follow established bridleways and link with the Swan’s Way. The ultra route uses a 49 mile line that passes the county boundaries at Threeshire Wood, adds a short section via Hanslope Village Hall to reach 50 miles, and finishes after a 12.4 mile loop around Grafham Water. The marathon route starts at Yelden and also finishes at Marlow Park, Grafham Water. GPX route files are provided.

Entries are open with fees of £75 for the 50 mile race and £40 for the marathon; affiliated club members receive a £2 discount. Minimum ages are 20 for the 50 mile and 18 for the marathon. Entries and transfers close seven days before the event. Pacers are not permitted. Race cut off times are 14 hours for the 50 mile and 8 hours for the marathon; progressive checkpoint cut offs apply.

Timing and tracking are provided; competitors receive trackers at registration and must return them at the finish. Professional first aid is available at start and finish and can access the course. Volunteers staff aid stations for hydration and nutrition.

Mandatory kit includes a charged mobile phone with organiser and medic numbers, a 1 litre water container, survival blanket, whistle, own cup, and for the 50 mile race a long sleeved base layer or fleece and reflective top or bands. Trail shoes are advised. A waterproof jacket is suggested.
