There are thrilling rides and then there’s the Giant Miler, one of the most demanding single‑day mountain bike challenges on the planet.

​Part of New Zealand’s celebrated Whaka100 MTB festival weekend, the Giant Miler pushes riders beyond what most endurance cyclists ever imagine attempting. Already in its short history, the Miler has earned a reputation not just for distance, but for the relentless test it lays on both body and mind.

​​There are two new names as winners of the UCI Marathon MTB National Championship, staged as part of the annual Whaka 100 event in Rotorua.

Rising 20-year-old Taupo cross-country rider, Coen Nicol from Taupo has prevailed in the elite men’s category, while accomplished Christchurch rider, Mary Gray has etched her name on the women’s trophy.

Expect new names on the trophies when the UCI Marathon MTB National Championships are decided in Rotorua this weekend.

When four-year-old Harvey Lette lines up for the Whaka 100 Mountain Bike Marathon this weekend, he'll have something in common with 77-year-old Trevor Swindells: neither of them had gears on their first bike.

For Harvey, it's called a balance bike. For Trevor, it's called the 1960s.

The 73-year gap between the event's youngest and oldest riders is what the Whaka 100 is all about - everyone's welcome, everyone has a go, and nobody cares if you're still working on your motor skills or your knees aren't quite what they used to be.

When Paul Gunn's friends and family line up for the 50km mountain bike race at this weekend’s Whaka 100, they’ll be carrying his memory with them - proudly wearing shirts with his face and the words “Ride with Gunnie.”

It's a fitting tribute to a man who spent his life encouraging others on the trails, sharing his expertise freely, and tearing through Rotorua’s forests at great speeds.

The Whaka100 team, in partnership with the Gunn family, is proud to announce the finalists for the inaugural Paul Gunn Scholarship, a legacy honouring one of the Whaka100 community’s most passionate and generous supporters.

There’s a reason the Whaka 100 weekend feels more like a festival than just a race and this year, it’s going next level. With the biggest expo in Whaka history landing alongside the largest rider field in our 18 year journey, the atmosphere at village is set to be absolutely electric.

​Two of New Zealand’s classic mountain bike participation events will double as Cycling New Zealand’s UCI Marathon MTB National Championships for the next four years.

Heavy rain overnight was no impediment for champions Craig Oliver and Olympian Sammie Maxwell who successfully defending their national titles at the 2024 Whaka 100 MTB Marathon in Rotorua today.

​Experienced mountain bike professional Rae Morrison and promising schoolboy Josh Cavanagh took out the respective elite honours in the MTB Eliminator National Championships, staged as part of the Whaka 100 event in Rotorua.

​Lining up at the start of the Whaka 100, there’s an air of nervousness as the morning mist lifts to reveal a clear, crisp morning and a sea of hardy souls gathered at the start line of a big day on the bike. Some will know what they’re in for, others will not have a clue. I know what I’m in for, but not exactly ready for it.

Sitting atop a bike in the middle of this crowd and scanning the scene, it’s obvious there’s quite the cross-section of society on the starting grid. I’m seeing every embodiment of nervousness, from nail-biting to full-belly laughs and a load of people generally fidgeting with nervous excitement.

Just who are these people, I wonder? My mind drifts, and I make my own assumptions:
