21km
Our toughest event, but full of rewards!
21kms of ups and downs and twists and turns.
Get yourself on the start line.
The 2025 course has been nearly completely redesigned and makes the most of the new and improved Craters Mountain Bike Park.
We’ve fine-tuned the course - this year’s half marathon is dialled in for accuracy! You’ll start from your own private (and secret) start line just 200m from Wairakei Resort.
The first kilometre is a gentle uphill before the real adventure kicks in. You’ll navigate nearly the full perimeter of the Craters of the Moon bike park, hitting the highest point at 8.5km - your own mini Everest. From there, the second half offers a little relief, including geothermal sections and a loop around the epic Craters boardwalk.
With under 6km to go, enjoy the twisty downhills (and yes, one last sneaky climb) before flying down to the finish.
