A major record tumbled at this year's Weet-Bix Kids' Tryathlon in Mosgiel, but it did not involve the fastest time or speed of a competitor.
Rather, it was a record number of participants, an event spokesman said.
"It was a sell-out event - 1485 participants. So that's a new Dunedin event record."
He said the event was first held in 1992, when it attracted about 800 entrants.
Entries of children aged 7-15 continued to increase and this year's entries sold 85% faster than in previous years.
The young triathletes swam, cycled and ran their way around Memorial Park and the Mosgiel Pool.
For crossing the finish line, all received a medal from Olympic and Commonwealth Games shooter Natalie Rooney, Paralympic gold medallist Anna Grimaldi and triathlete Janus Staufenberg.
"It's all about participation. Everyone gets a medal.
"It's really designed as a confidence-builder so kids can get out there and do something for their own personal achievement, as opposed to being the fastest around the track.
"This event is really a starter event for a lot of kids and they'll go on to do more competitive things from here."
