The swim takes place in Box End Lake. The lake is primarily used for wakeboarding, so contains lots of wake-boarding jumps. The route is one, two or three laps of a 750m clock-wise oval around the lake, between the jumps.

The NEW Sprint bike course is one, fast 20.1km lap

The NEW Standard bike course is one, fast 40.2km lap

Middle Distance bike course

The Run route is roughly 100m from transition to a 5km loop which the competitors do once for the sprint, twice for the standard and four times for the middle distance,  before a 100m run into the finish making the run distance 5.2k, 10.2k or 20.2k. The route is completely off-road, but is very changable, which makes for fantastic and exciting racing, and the multi-lap format enables great support and encouragement as you pass transition.

Swim – Open water | Bike – Road | Run – Off-road

We actively welcome support and involvement from local communities, businesses and individuals. If you would like to find out more about marshalling, sponsorship or group bookings please contact us at the address below.
