"This is the first time we've put on this distance so we're still figuring the event out but it's a great course," Mr Hook said.
"It's not an easy course to be fair as [you cycle] right up Tarawera Rd, but it's a nice stepping stone for people looking to build their confidence up. They get most of the hard parts."
There is also a teams option for both distances. Spectators can watch action from the lake or bike course. There is ample parking at the lake and competitors will circle the lake twice on the run.
"The money raised will make a huge contribution towards running the Rotorua Hospice service, which is provided free to patients and families living with terminal illness in our community," said Rotorua Community Hospice general manager Sharron Black.Late entries, which are $150, are being accepted at Avantiplus, Amohau St, on Friday until 9pm.
