The Hunua Ranges event in the Auckland Trail Run & Walk Series takes place at Upper Mangatawhiri Camp Site, southeast of central Auckland. This is part of Trail Events NZ's yearly winter series, which typically holds Auckland-area trail events within an hour's drive of the city. This particular event provides a 6.3K short course and a 13.5K mid course for runners and walkers, alongside run-only long and super-long options of 19.4K and 24.2K.
The structure emphasizes participant choice: each event in the series offers short, mid, long, and super-long distances, allowing individuals to select from a manageable off-road walk to a challenging trail run exceeding half-marathon distance. The event is cupless, requiring all participants to bring a reusable cup, bottle, or hydration pack for water refills. The Hunua location lends this event a more remote, back-country atmosphere compared to a city park event, while still adhering to the series' aim of providing accessible trail running days around Auckland.
