There will be a separate race happening on marathon day but it won't be about who can be the fastest.
The five Rotorua Rotary clubs have teamed up to raise $50,000 for the Rotorua Community Hospice endowment fund but there's secrecy among them as to how well their efforts are going.
The five clubs - Rotorua, Rotorua North, Rotorua West, Rotorua Sunrise and Rotorua Lakes - have been challenged to see how much money they can raise and how many of their members and associates they can get around the 42km course.
Runners and walkers are being sponsored and have been challenged to raise $1000 each.
Project leader Deb Bell said this was the 50th Rotorua Marathon and an ideal opportunity.
