2026 Langdale Marathon - Oct 17

Two laps of the Great and Little Langdale valleys on open single-track roads marathon course in Great Langdale with 1035m elevation gain. Severely hilly and relentless, not a PB course. The route circles the Langdale valleys anti-clockwise and tackles the savage 1-in-4 climb to Blea Tarn twice, for roughly 1,035m (3,418ft) of total ascent over the full marathon. Expect to finish well outside your flat-road marathon time
