The Marathon Series is designed to outlast other ropes in extreme conditions, where durability is paramount: Big walls, multi-pitch climbs, institutional usage, remote first ascents—all these types of climbs require something extra. The Marathon Series is made up of 5 rope models, each designed for a specific purpose but all come with the thicker and more durable Marathon sheath construction for greater longevity and durability.
10.1 mm // Well built, not overbuilt. The Pro is designed for the demands of professional guides. Its long-lasting exterior is specifically designed to stand up to wear and tear.
10.4 mm // Able to handle the hard abuse of big wall climbing—with run-outs, big falls and demanding maneuvers, the Sport’s toughness excels on the biggest, boldest sends.
10.7 mm // Ideal for institutional uses, like climbing programs or challenge courses, the sturdy construction of the Ultra has an ideal diameter for novice belayers.
