ZACH MACH is a Multisport Event for the weekend warrior to the elite, for ages 7 to 107+ in Mackay’s great outdoors based around Adventure, Community and Health.

Brace yourself for the ultimate dirty, muddy, and wet challenge on May 11th and 12th! Conquer nature's obstacles, navigate through mud-soaked trails, and embrace the thrill of facing the elements head-on. It's not just a race; it's a choose-your-own-adventure extravaganza!

Register for ZACH MACH or MINI MACH Adventure Challenge as an individual, pair, or relay team. Opt for the stages that speak to your adventurous soul, conquer them, and stand tall as you compete for prize money in every chosen stage. Your adventure, your rules!

ZACH MACH celebrates the life of Zach Roberts, an outstanding young man who embraced adventure and people. He was a much loved grandson, son, brother and former student from Mackay Christian College who tragically passed away in a traffic accident at the age of 18.

Celebrate the life of Zach Roberts and join us for the 2025 ZACH or Mini MACH Adventure.
