Overview
The Kathmandu Coast to Coast is New Zealand's most iconic endurance event. First run in 1983, it crosses the entire South Island — from Kumara Beach on the Tasman Sea to New Brighton Beach on the Pacific Ocean — via 3 km beach run, 55 km road cycle, 33 km mountain run over Goat Pass, 15 km cycle, 70 km kayak on the Waimakariri River and a final 70 km ride into Christchurch. Two Day, One Day and the Longest Day (individual, non-stop) formats accommodate everyone from first-time multisporters to Coast to Coast legends.
A rite of passage in New Zealand endurance sport. The beach start under mountains and the Pacific finish are unforgettable.
