Altra Kielder Marathon Weekend

The event is a multi race running weekend held at Kielder Forest Park in Northumberland in early October 2026. The main marathon follows an almost entirely off road course around Kielder Water, described in the event materials as northern Europe’s largest man made lake.

The weekend includes several separate races and youth events. Distance options on the programme include:

  • Marathon
  • Half Marathon
  • 10K
  • Gravel Duathlon
  • Junior races

Event services and facilities listed for participants and spectators include a medal and goody bag for all finishers, a free Park and Ride system for runners, a spectator pass priced at £3 for the day with shuttle buses to multiple vantage points, secure baggage drop, and local food and drink available on site. Prizes are awarded to the top three male and female finishers and to the first veterans in V40, V50, and V60 categories.

The location entry gives an address at Kielder Forest Park, Hexham NE48 1BT, and the organiser lists a range of race prices and a discount for members of UKA clubs. The programme spans competitive and junior events over several days, with route maps provided separately for each distance. Visit the organization's website for the most recent information.
