About $20,000 has been raised since the classic started seven years ago, with all the funds returned to the Taieri Mouth community.
The event has grown significantly, from its humble beginnings when 127 competitors contested the inaugural event, to a peak of about 330 competitors in 2008.
But, this year, organisers added a walk-run event to attract a larger cross section of people, and the overall field swelled to about 550.
"It is as much a fundraising event as it is to get people out [to enjoy Taieri Mouth]," co-organiser Wayne Jopson said, adding that while revenue had gone up, so had the cost of staging the event.
"It will probably be another month until we know [what was raised]. I think we'll find our costs are up about 50%."
All profits would be given to the community, he said.
Taieri cyclist Brad Evans was the fastest of the men in the 42km mountain bike event and Ray Hope dominated the 62km race.
Maggie Paesk won the women's open 42km race and Kate Fluker took the honours in the 62km event.
Otago distance runner Sarah Chisnall won the women's 12km run, while Kevin Duggan won the men's title.
Other notable winners were Graeme Egan and Julie Edmunds in the men's and women's 12km recreational walk.
Mountain biker Brent Johnston sustained "very minor" injuries, but a helicopter flew him to Dunedin Hospital on a routine return flight, a St John spokesman said.
