The course is set around a 10km loop - the one half along a gravel road and the other half on a forest track beside the water race that gives the event its name. Originally the water race was built for gold mining around 1860 and now it provides the water supply to the town of Naseby.

Stay on the left of the traffic cones taking care for oncoming runners , sharp right then back up to the Water Race, then keep following it past the swimming dam, until you reach a bridge crossing the Water Race. Left over the bridge, another left at the Stone marker then a sharp right onto Translator Rd. Follow the gravel Rd up to Ramp Rd, left down there and then left again into Wet Gully Rd, a short jog and that is lap 1.
