The current edition of this event is on 24 to 25 August 2018.
The Great Naseby Water Race is an annual ultramarathon event from Friday, 25 August to Saturday, 26 August 2017 with multiple laps around a 10km course.
New for 2017 is a 200km race, and the 60km team relay returns after taking a break in 2016.
The course is set around a 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.
