Economic benefits of about $2.7 million are estimated to have flowed into the Upper Clutha region on the back of the Challenge Wanaka long-distance triathlon.
The results of a survey of more than 800 people associated with the 2010 event has delighted race organisers.
It is estimated that about 6000 spectators watched the event and its 1,015 entrants on race-day.
Each athlete brought an average of 4.6 people with them to the event, with more than 40% of the entrants visiting the region prior to the race and staying an average of 5.5 days.
Challenge Wanaka director Victoria Murray-Orr said any benefits associated with pre-event visitors for training purposes were not included in the $2.7 million.
"We're delighted with the results ...
On top of the direct benefit highlighted by the survey, we have over 1000 happy athletes heading away and saying great things about Wanaka, thanks to the wonderful welcome the community gave them," she said.
The survey, taken by 610 athletes and 200 race-day spectators, covered three main topics: length of stay, spending habits and satisfaction levels.
About 79% of athletes surveyed and 83% of spectators came from outside the Southern Lakes region.
Demand for food, drink and accommodation was high, with these sectors accounting for the bulk of spending.
The survey confirmed the event's importance to the region and generated feedback which would be used to further next year's Challenge Wanaka, Ms Murray-Orr said.
The event received "extensive" media coverage in Europe, the United Kingdom, the United States and Australia, "all of which contributes to the tourist dollar", she said.
Competitors and spectators listed challenge Wanaka's location and atmosphere as the main attractions and 96% of competitors would recommend the long-distance triathlon to other athletes.
