Fully marked & marshaled trail races over 10k and Half Marathon distances

10k and Half Marathon distances on the glorious trails and tracks surrounding Pitsford Water.

The half marathon route also visits the beautiful local villages of Holcot, Hannington, Walgrave, Old, and Scaldwell.

Race information

Starting and finishing at Brixworth Country Park, the 10k race provides the perfect introduction to trail running whilst the half marathon provides a decent challenge for those looking to go further or build their experience of trail running.

The routes enjoy the best of the Northamptonshire countryside as well as having some fantastic views.

Entries

Minimum age for entry on race day is 16 years old for the 10k and 17 years old for the half marathon.

The race cut off time is 4 hours for both races.

As the races use footpaths across farmland, running with dogs is not permitted.

Entries, and transfer of entries, will close 7-days before the event.

New for 2027!

Both routes leave Brixworth Country Park, heading across the dam towards Pitsford, then pick up the trails above Pitsford Water towards the village of Holcot.

The 10k route then heads downhill and over the causeway to join the track alongside Pitsford Water back to the finish at the country park.

The half marathon route heads through the village of Holcot and picks up the trails up to Hannington, across to Walgrave, Old, and Scaldwell, before dropping back down to join the track alongside Pitsford Water for the final mile.

Please note: there are a number of stiles between fields to negotiate on the half marathon route.

No in-ear headphones will be allowed at this event. Headphones that work by conducting sound through bones and do not sit in the ears are allowed.

On-course support

As with all Race Harborough events, there will be professional first aid on hand at the start and finish with the ability to access runners on the course. Race Harborough volunteers will also be on-course to provide hydration at 3 water stations on the half marathon route (at miles 3 – Holcot, 6.5 – Walgrave & 9.5 – Scaldwell) and 1 water station, at mile 3 – Holcot, on the 10k route. Water will also be available at the finish.

Kit

Trail shoes are advisable, or shoes with some grip.

Mandatory items:

Full charged mobile phone including the numbers of the Race Director and Race Medic (half marathon)

Our races are cupless, so you will be required to bring your own cup

Whilst the above are the only mandatory items, you may also like to consider the following depending on the weather conditions on race day.

Waterproof jacket

Long sleeved base layer

Hat and gloves

Prizes

There will be prizes for top 3 male and female finishers in both races, and all finishers will receive a specially commissioned race medal.

Supporters

The best place for your friends and families to support you is alongside the tracks at Pitsford Water. Whilst the half marathon route does run through a number of local villages, these villages are small and have very little parking (other than that for the villagers themselves) so we would ask that any support is limited to the tracks alongside Pitsford Water in order to maintain the support of the event from the local villages.

Free race photos!

As with all Race Harborough events – you don’t pay for your race pics! Free digital downloads of your race are available to download soon after the event finishes and we’ll announce their availability on our Facebook page.

Charity

For 2026, the main focus of our charity support will continue to be the Jubilee Foodbank, Market Harborough, and the Weston Favell Centre Foodbank, Northampton. Everyone who enters a Race Harborough event will be given the opportunity to make a donation to support these good causes and, we hope, our event community will rise to the challenge and help make a difference to those that need it most.
