It is going to be multi-sport mania at the Redwood/Whakarewarewa Forest and Tikitapu (Blue Lake) on Sunday.
More than 700 people are expected to take part in 10 different physical challenges.
From the 2km fun run for Under 10s, to the 50km premier challenge, all age groups and fitness abilities are catered for.
Race director Adrian Bailey prides himself on providing opportunities for all fitness levels to "get out and have a go" at events combining running, mountain biking and kayaking.
"If you are not ready for the 50km, we have the 25km and people can enter as individuals or have the option of entering as teams to share the load," he said.
