Original Mountain Marathon

Test the very essence of mountain skill and self-reliance at The OMM on October 24-25, 2026, the legendary two-day, unsupported adventure that has set the gold standard for UK mountain challenges since 1968. This iconic event, held in a new, secret Scottish location each year, pits teams of two against 40-100km of rugged terrain, demanding expert navigation, meticulous campcraft, and pure resilience over a remote overnight bivouac. More than a race, it's a profound journey where you carry everything you need to survive and compete, mastering Harvey maps and mountain weather in a true test of partnership and wilderness proficiency. With its unique blend of elite competition and accessible course options, The OMM attracts a dedicated community of adventurers united by a shared passion for the mountains and a requisite sense of humour in the face of inevitable hardship. The unforgettable weekend culminates in a post-event hot meal and the deep satisfaction of having tackled one of the most authentic and respected challenges in the outdoor world.
