25K Quad Extender Fun Run 2026

The 25K Quad Extender Fun Run is a 25 km trail race held around Tunnel Gully in Upper Hutt, New Zealand, with entries opening in June. It is part of the WAI Run Festival and is suited for runners seeking a hilly off-road course over a flat road race. Younger participants are welcome: under-18s require parental consent, and under-14s must be accompanied by an adult. The course begins and ends at the Upper Picnic area, sharing this location with the 12 km race. Participants will navigate Tunnel Gully trails and encounter significant elevation gain. The 25 km route features a sprint finish at Mt Climie. Due to forestry operations potentially impacting the Station Drive, Goat Rock, and Taniwha areas, the 25 km course might utilize lower mountain-bike trails on the return journey, maintaining a comparable distance with slightly reduced climbing.
