The fourth leg of the Ekiden is the longest, just. This part of the course is mostly rural running alongside State Highway 33 (which becomes SH30). There is a good sized shoulder most of the way but you should be careful the closer you get to town as traffic will increase later in the day.
This leg starts out flat on Hamurana Rd, running directly away from the lake. A right turn takes you onto the state highway and at 1.5k’s in, you hit bridge over the Ohau Channel – the waterway between Lake Rotorua and Lake Rotoiti. From there, the course climbs to 3k’s in and then drops back down. The last 4km to the airport are flat.
