Come and take part in the UK's Premier Night time trail running series based at Kielder Resevoir. Trail Outlaws offer a unique experience and running challenge like no other. Kielder resevoir is set in a waterside park. That is actively maintained and shared with the public by Nothumbrian Water - Living Water.

Distances at the event range from 10K to marathon distance.

We are passionate about staging fun, inclusive and challenging trail runs in the darkest of places. That's why we have hand picked Britian's most beautiful Dark Skies Parks to host our events. Whether you're new to the trails or a regular, come and try our Dark Skies Run events for a new and unique challenge. We promise you won't regret it.
