Helping athletes get to the Coast to Coast
Interislander is proud to flex our sponsorship muscles for the Kathmandu Coast to Coast event, New Zealand's premier multi-sport challenge.
This sponsorship, plus discounted fares for competitors, underscores our commitment to supporting athletes who test themselves against some of the most demanding terrain and conditions our country has to offer.
About the Coast to Coast
The Kathmandu Coast to Coast is a gruelling event spanning 243 kilometres, starting in Kumara on the West Coast and finishing at New Brighton Beach Pier in Christchurch. Involving running, rock-hopping, kayaking and cycling, this race is a rite of passage for many Kiwis and a top event for elite athletes worldwide.
How we support the Coast to Coast
Interislander is deeply connected to the spirit of the Kathmandu Coast to Coast. We understand the intense effort, determination, and dedication required to compete. As a sponsor, we take great pride in helping athletes get to the start line.
We sponsored Campbell Gray again in 2026 as he prepared for the race. See Campbell’s story.

Campbell Gray's Coast to Coast Journey
Campbell Gray completed the ultimate Kathmandu Coast to Coast race - the Longest Day in 2025. He finished 16th out of 222 competitors in a time of 12:58:24.
Known as one of New Zealand's most gruelling adventure races, The Longest Day takes competitors across 243 km of rugged terrain from the West Coast to Brighton Beach in Christchurch, all in one day.
In February 2024, he took 3rd place in his category of the two-day event.
However, 2025 was a whole new challenge as he took on the single-day, non-stop endurance race, which includes biking, running, and kayaking through stunning, yet punishing landscapes.
Interislander has sponsored Campbell for three years in a row, including supplying him with a branded kayak and travel.
“Interislander has been my first sponsorship and it’s pretty cool.”
