Dark Skies Run Race Series

The Dark Skies Run Race Series is a set of night trail races organised by Trail Outlaws at Kielder Waterside. Kielder holds gold tier Dark Sky Park status from the International Dark Sky Association (December 2013), which is central to the event concept of running under clear, dark skies and visible stars.

The series offers several distance options and associated entries. Entry prices range from £23 to £65 according to the available offers. The event is staged as an offline, in-person race with on-course aid stations, volunteer marshals and route waymarking. Race headquarters features a heated tipi at the start and finish on some occasions, and refreshments are available for purchase.

Participant feedback collected in reviews notes consistent strengths in organisation, atmosphere and volunteer support. Common observations include well placed aid stations and friendly marshals, alongside repeated suggestions for clearer directional signage to and from the car park and at specific turns. A few runners reported small differences in advertised versus actual distance on longer routes and requested clearer finish area layout. The event format includes night running using headtorches and running on established trails around the reservoir area. Visit the organization's website for the most recent information.
