This year's Motatapu comprised the 15km Arrowtown.com Miner's Trail; the R&R Sport adventure race, the Speight's Summit mountain bike, the Icebreaker 42.2km off-road marathon and the inaugural invitation-only half ironman.
It was one of the busiest days annually in Arrowtown.
Parking - and seats in restaurants and bars - were at a premium all day and well into the evening, crowded by competitors, supporters, volunteers, staff and onlookers taking in the action at the Butler's Green finish line and partying into the night.
After the prizegiving on Saturday afternoon, hundreds of people stayed on to celebrate at a free concert by some of Christchurch's top music acts, to raise money for the Christchurch earthquake appeal.
Fur Patrol's Julia Deans, Flip Grater and Andrew Keoghan, with Ben King of Golden Horse and the Unfaithful Ways, along with Barry Saunders from the Warratahs, entertained the crowds until after sunset.
Eight hundred competitors from Christchurch made the journey south to compete, including some who had lost everything during the magnitude 6.3 earthquake last month.
Among those running in support of Christchurch was Air New Zealand chief executive Rob Fyfe, who is training for Everest Base Camp, which he is attending in six weeks.
"It was really, really good fun," Mr Fyfe said.
"The scenery is just stunning and we couldn't ask for better conditions.
"It's great to see so many people from Christchurch here."
Biking in support of Cantabrians was Christchurch-based multisport athlete Steve Gurney, who has won the Coast to Coast race a record nine times and who completed the mountain bike on Saturday in 2hr 12min 27sec.
Gurney travelled to the district despite having lost his home and possessions in the February 22 earthquake.
Sally Hickering, of Christchurch, completed her first marathon on Saturday.
"If there is one thing this earthquake has taught us, it is the importance of living each day to the max. You never know what is around the corner, or what tomorrow may hold."
Others entered the events raising money for Pink Pilates and Wonder Walkers.
More than 100 entrants in the Motatapu events were part of Team Pink Pilates, raising money for the Pink Pilates Trust, which supports a rehabilitative programme for New Zealand women recovering from cancer.
Dunedin Pink Pilates physiotherapist Kerry Tutty, who competed on the Miner's Trail.
Supporters of Pink Pilates wore pink shoelaces to symbolise taking the first steps on the road to recovery.
All funds raised on Saturday would go towards funding women in Canterbury.
It was hoped to be able to give $10,000 from the event.
Former world squash champion Dame Susan Devoy walked the 42.2km marathon for her recently launched Wonder Walkers, an initiative which encourages women to become more active through walking.
She also walked in support of Team Pink Pilates.
