The Great Naseby Water Race (GNWR) is an annual ultra marathon event from 26 to 29 August 2026 with multiple laps around a 10km course.

The course is set around a figure 8 10km loop - the first half along a gravel road and the second half on a forest track beside the water race that gives the event its name. There is no actual water running.

This unique ultramarathon event takes place near Naseby - the highest town in New Zealand at 2000ft. Naseby is 15km north-west by road from Ranfurly and 145km north-west (via Middlemarch) from Dunedin. It is held on the last weekend of August each year. Run solo or in a team relay.

The event is managed by the Naseby Development Charitable Trust. Refer to the event website for start times, etc.
