World-ranked rider Samuel Gaze was the first man to cross the finish line, completing the track in five hours, 13 minutes while Kim Hurst was the first woman to reach the end, coming in at the six-hour, 30-minute mark.
Farmer said this year's race was a wet one but the track did not get muddy or boggy.
"This year was probably the worst weather we have ever had and coupled with the new track, it would have certainly put extra time on the riders. For the front riders it was probably another half an hour and for the everyday rider, it would have been about an hour and a half.
"It was a mentally tough day but that made it all the more rewarding for people when they crossed that finish line. This race is meant to be one of the toughest in the southern hemisphere, even in the best weather, so this year we have definitely delivered on that promise."
He said the course provided a great contrast of groomed handcrafted trails to rugged back-country mountain bike bliss. "We will stick with this new track for the next couple of years and see how it goes. Mountain biking is definitely a growing sport in New Zealand and we have big plans in store."
