Altra Kielder Marathon Weekend

The Altra Kielder Marathon Weekend brings a full programme of trail running and multisport action to Kielder Water & Forest Park in Northumberland. Marketed as Britain’s Most Beautiful Marathon, the headline race follows an almost entirely off‑road route around northern Europe’s largest man‑made lake, delivering sweeping views, forest tracks and a friendly festival atmosphere. Across the weekend, participants and supporters gather at Kielder for a scenic escape that blends challenging courses with a welcoming event village.

The schedule features the Marathon, Half Marathon, 10K, Junior runs and a Gravel Duathlon, giving options for all abilities while keeping the focus firmly on trails. Runners can expect medals and a goody bag at the finish, plus on‑site refreshments and a free park‑and‑ride system for entrants. Spectators are catered for with affordable shuttle passes to vantage points, helping create lively support across the routes.

Set within the vast Kielder Forest, the weekend highlights the area’s natural beauty while maintaining straightforward logistics. Organised by Events of the North, the experience balances memorable courses with practical touches such as secure bag drop and clear pre‑event information. Whether chasing a time or savouring the scenery, the Altra Kielder Marathon Weekend offers a rewarding autumn adventure in one of England’s most distinctive outdoor settings.
