WELCOME TO ZACH MACH ADVENTURE CHALLENGE

From 8-9 May 2027, Mackay’s beautiful Pioneer Valley will come alive with the heartbeat of weekend warriors racing across more than 88km of rainforest, cane paddocks, river crossings, dam waters and MTB trails in pursuit of the holy grail: podium finishes and prize money.
