Original Mountain Marathon

OMM develops technical outdoor equipment and apparel specifically engineered for fell running and mountain sports from its UK base. The company's core products include the signature Fell Shoe, Rotor Smock, Core Fleece, and Mountain Raid Hooded Jacket, each certified through their internal "Fell Approved" testing protocol. These items undergo field testing in British mountain conditions to verify durability, thermal regulation, and compression characteristics. The brand maintains official partnerships with GB Climbing and British Orienteering through its "Made For This 2026" athlete development initiative. This program provides gear and support to competitive athletes training for the Commonwealth Games and other elite mountain sport events. The initiative spans multiple disciplines including fell running, orienteering, and competitive climbing. OMM's product development process integrates feedback from sponsored athletes competing in fell races, mountain marathons, and climbing competitions. The company's technical specifications emphasize minimalist design, weather protection, and packability for self-supported mountain activities. Their equipment serves both recreational outdoor users and competitive athletes requiring certified gear for sanctioned events.
