Marathon Series

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.
