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.
10.1mm // Well built but not overbuilt, the Pro is designed for situations where durability and lightweight maneuverability must coincide.
10.7mm // Ideal for heavy-duty institutional use, the sturdy construction of the Ultra has an ideal diameter for easy handling.
11.2mm // When weight isn’t a factor, the Mega is your big, burly, Herculean rope. The incredible durability and abrasion resistance of the Mega is ideal for military and industrial dynamic rope use.
