Trail races in United Kingdom
From the chalk ridges of the South Downs Way to the granite tors of Dartmoor, from Welsh mountain crossings to Scottish Highland loops, trail running in the United Kingdom draws on centuries-old paths through ancient forests, open moorland, and dramatic coastal landscapes. Events range from accessible woodland half marathons in the New Forest and Ashdown Forest to demanding multi-day ultras like the 1,374km Land's End to John O'Groats, with the Brecon Beacons, Chiltern Hills, and Snowdonia providing classic British mountain terrain.
