Grafham Water Trail Races
Grafham Water Trail Races on Sunday 11 October 2026 are fully marked and marshalled trail events based at Marlow Park, Grafham Water, Huntingdon, Cambridgeshire PE28 0BH. Routes use local trails and sections of the Three Shires Way and offer views of the reservoir and surrounding Cambridgeshire countryside.
Distances
- 10k
- Half Marathon
Both routes leave Marlow Park heading west toward Easton; the 10k loops back onto the outward bound track while the half marathon continues with a large lap of the reservoir. GPX files are provided for both routes. As the courses use footpaths across farmland, running with dogs is not permitted.
Entries are open with prices set at £25 for the 10k and £30 for the half marathon. Minimum ages on race day are 16 for the 10k and 17 for the half marathon. Entries and transfers close seven days before the event. Both races have a four hour cut off.
On-course support includes professional first aid at the start and finish with access to runners on course, and Race Harborough volunteers supplying hydration at three water stations on the half marathon and one on the 10k; water is also available at the finish. No in-ear headphones are allowed; bone conduction devices are permitted.
Trail shoes are advisable. Mandatory items include a fully charged mobile phone with the race contacts and a personal cup. Prizes will be awarded to the top three male and female finishers in each race and all finishers receive a commissioned medal. Pre-ordered race merchandise is available prior to the event and free digital race photos will be supplied after the event. The event supports Jubilee Foodbank Market Harborough and Weston Favell Centre Foodbank Northampton with an option for entrants to donate.
