Event organiser Owen Smith, of the Rotary Club of Kerikeri, said the addition of the Missionary Trail had broadened the scope of the event and made it more attractive to locals.
"We have a core group of top-flight athletes who relish the challenge of the coast-to-coast Northern Crossing," Smith said. "We wanted to make the challenge of the event a little more do-able for the average Northlander and, with the Missionary Trail, I think we've achieved this."
Overall, the event comprised a triathlon, duathlon and a shorter course for people looking for a middle-distance event.
