Despite the wet and cold weather, the hardy competitors – aged from eight to 17 – put their sporting limits to the test at the Craigavon Lakes event.
The triathlon started with a swim, followed by a bike race and ended with a run, with five age categories.
The event was marshalled and coordinated by Down Triathlon Club with additional support from surrounding clubs and community groups.
Photographer Tony Hendron was there to snap some of those who braved the weather for the endurance event.
