WAI2K Trail Running Festival 2026

The WAI2K Trail Running Festival takes place at Tunnel Gully in Upper Hutt, bordering Wellington’s rugged hill country. This festival offers trail running distances ranging from a 12K fun run to a 100K ultra or relay, accommodating walkers, beginners, club runners, and experienced ultrarunners. The 12K is a quick loop on forest roads, mountain-bike trails, and creek crossings. The 25K introduces a more challenging middle distance, including Mt Climie, native bush, and tunnel trails. The 50K route crosses ridgelines, river valleys, and technical descents. The 100K is the most demanding event: a remote, high-elevation point-to-point course from Greytown to Upper Hutt. It has cut-offs and requires a full ultra kit, with options for solo runners or team relays.
