About Altra 13 Valleys
Altra 13 Valleys brings trail running to the heart of the Lake District National Park across a full weekend from 25 to 27 September 2026. Based at Theatre by the Lake in Keswick, the event offers four distances to suit different ambitions: 22.4 km, 58.4 km, 110.3 km and 184.3 km. All routes wind through the region's lakes and valleys, taking in mountain and valley views across demanding terrain.
Organised by Great Run in partnership with the Lake District National Park, the event is structured with generously set cut-off times and well-stocked checkpoints along the way. The longer distances include night running sections. Optional recce days are available ahead of the weekend, and the event welcomes both runners and walkers across all abilities.
