Entries Now Open

Make your Kielder visit into a weekend of fun! Held in conjunction with the Kielder Dark Skies 10k Night Trail Race on Saturday evening & the Kielder Off Road Duathlon the following day.

The Kielder night trail run is open to all abilities of runners. You will be tackling some of the amazing trails that Kielder Forest has to offer including single track, open forest tracks and even a 'bit' of mud! All runners must run with a head torch and suitable trail shoes. Kielder's weather climate in January will add to the fun! You will either be running in snow, rain or if your lucky a lovely crisp evening under the stars in the dark skies of Kielder.

“Northumberland International Dark Sky Park is England’s first Dark Sky Park and the largest expanse of dark night sky in the whole of Europe, thanks to minimal light pollution” (Source: Visit Kielder).

According to the Campaign for the Protection of Rural England (CPRE), the star-studded skies above Kielder Water & Forest Park are the darkest in England.

The best time for viewing is during the winter months, when the nights are darkest. Combine this with an awesome trail running route on a great mixture of forest trails then what further incentive do you need to pack your head torch, some warm winter gear & experience this amazing night run set in the beautiful confines of Kielder Forest.

10k Course: Starting from Kielder Castle, formerly the hunting lodge for the Duke of Northumberland, the route initially follows the 'Duke's Trail' for the first few miles on a mixture of surfaced roads & forest paths before returning through the grounds of the Castle.

Then it’s back out, past the Minotaur Maze picking up the trail through Viaduct Wood along the banks of the River North Tyne. This leads onto a loop which initially crosses underneath then across the historical Kielder Viaduct. The route then follows the course of the old railway line alongside Bakethin Nature Reserve, leading onto a section of the Lakeside way multi-user trail to reach Bakethin Weir.

The route now follows the forest road leading up a steady climb past Devil's Lapful to reach the junction at Castle Hill. This is followed by an exhilarating single track descent to reach ‘The Duchess Trail’ running alongside Kielder Burn. Cross the old pack horse bridge returning back to Kielder Castle to a well deserved finish.


10k Course: 


Total Ascent: 205m 


Terrain: A great combination consisting mainly of forest roads, gravel trails & woodland singletrack. Some uneven sections of grass with exposed tree roots. Long moderate slopes with some steeper sections.


10k Time Limit: 2.5hrs.
