Race Harborough
On Sunday, 11th October 2026 I am organising the Grafham Water Trail Races - 10k and half marathon running races - that start and finish at Marlow Park, Grafham Water.
You can view the routes here:
10k route: https://ridewithgps.com/routes/53742966
Half marathon route: https://ridewithgps.com/routes/55367789
The half marathon starts at 09:00 and the 10k at 09:15.
As you can see, both routes head out of Marlow Park on the main path, before joining the trails along the shoreline at Church Hill Bay and Farm Bay, before the routes split after passing Hill Farm (just before 2 miles on the half marathon route and just after 3k on the 10k route).
At the split point the 10k route bears right onto Hartham Street before turning right onto Easton Road for a brief moment, before turning right back onto the trails and joining the Three Shires Way by West Wood before bearing right across the footpath and onto Church Road. The route then proceeds along Church Road towards Grafham Village, before turning right onto Church Hill. At the end of Church Hill the route turns left and follows the main path on Grafham Water back to the finish at Marlow Park.
The half marathon route, at the split point, continues on the trails around Sanctuary Bay, Savages Creek, before running the trails in an ’S’ shape alongside Littless Creek, Dudley Creek, Valley Creek, and above Perry West Wood. At 6.5 miles the route joins the Three Shires Way towards, and through, Dillington Village. It then continues along the Three Shires Way, past Midloe Grange, before deviating slightly, before Honey Hill Plantation, to use a section of footpath, before joining the Three Shires Way again by Highfield Farm, across the B661, and onto Grafham Water to the finish.
Signing of the routes will take place on Saturday, 10th October, so you may see a number of small yellow and black arrows appearing along the routes, and a number of warning signs for road users put in place.
These will all be removed immediately after the event.
It would be really appreciated if you could make residents of the village aware of the event via your website and/or parish magazine.
Full information on the event is available on our website: https://raceharborough.co.uk/grafham-water-trail-races/ but if there is anything further you'd like to know, please don't hesitate to get in touch.
Yours sincerely,
