Fun. Safe. Mighty.
Tri-ActiV8 Kids Triathlon 2026
Mackay’s dedicated, non-competitive triathlon built to give kids aged 5–12years boundless confidence in the water, on the bike, and running across the finish line.
100% About Fun, Zero Pressure
This event is all about celebration and finishing with a smile. Kids are never timed and do not wear ankle or wrist chips. Fast or slow, walking or sprinting, every child moves at their own pace—supported every step by our encouraging Pink Army of Volunteers!

Safe Courses Parents Can Trust
🏊 1. The Pool Swim
The swim is in the 25m pool. Kids will need to be able to swim the allocated distance unassisted. Tri-ActiV8 volunteers will be pool marshals ensuring safety.
🚴 2. The Bike Course
The ride is within the safety of the MARC and University. If a chain falls off or a tyre goes flat, a volunteer rider will assist and get them back in the fun!
🏃 3. The Track Run
The run is on the state-of-the-art tartan running track. Parents have lots of opportunities to cheer your child from the sidelines!
