Mud, mateship and meaning: Why two doctors keep returning to the Cardiac Challenge

It began with a bit of peer pressure, the chance to explore some of Far North Queensland’s most remote communities, and a mission to bring heart care closer to those who needed it most.
Fast forward a few years, a few flat tyres, and a few thousand kilometres, and for Cairns-based anaesthetists Dr Zach Tappenden and Dr Andy Potter, the QSuper Cardiac Challenge has become far more than a weekend ride – it’s become a powerful reminder of why they do what they do, and who they’re doing it for.
The pair are part of a team of clinicians known as the Gas Monkeys, who tackle the 333-kilometre journey from Cairns to Cooktown each September. And while it may have started as a bit of fun, the team has grown into one of the ride’s most committed and recognisable crews - bringing energy, heart and a deep sense of purpose to every kilometre.
More than just a test of endurance, the QSuper Cardiac Challenge is a lifeline that has raised millions of dollars over the years to deliver specialist equipment and outreach services to hospitals across the state’s Far North. For patients in remote communities, it can mean the difference between travelling hundreds of kilometres for treatment, or receiving care closer to home.
Dr Tappenden first joined the Challenge in 2018, encouraged by a few colleagues and the promise of a good cause. At the time, he didn’t see himself as a cyclist - but with a few triathlons behind him and a sense of adventure ahead, he decided to give it a go.
One ride quickly turned into many, with the dedicated Gas Monkey missing just one ride since then to get married.
“It just stuck. There’s something really special about the people, the places and the purpose that keeps bringing you back,” he said.
Dr Potter came into the fold a couple of years later after what he described as a “fair bit of peer pressure” by colleagues who had fallen in love with the fast-growing charity ride.
“I wasn’t sure what I was getting into. But once I was out there and rode through those communities, I understood exactly why people keep coming back year after year. It makes a difference,” he said.
“You realise just how far care can feel. It really hits home.”
Each year, riders of the Cardiac Challenge are grouped by pace - from the slow-and-steady to the seriously swift - with support crews, signage and rest stops tailored to every speed. The Gas Monkeys ride in what’s known as Pack Two, a faster group that averages between 27 and 30 kilometres an hour.
It's fast enough to keep things moving, but never at the cost of camaraderie. And that culture is alive well beyond the road. The pair said over the years muddy tug-of-wars in rodeo rings, makeshift campsite rituals, and the occasional test of bravery in a far-too-narrow portable toilet have all become part of the experience.
“There’s no room for pride out there,” Dr Potter said.
“You get sweaty, you get tired - and then someone hands you a sandwich and you’re laughing again. That’s part of what makes it great.”
But beneath the dust and light-hearted moments is a clear, driving purpose - one both clinicians see every day in their hospital roles.
“The cardiac outreach program wouldn’t be what it is without this ride,” Dr Potter said.
“We’re talking about ECG machines, portable ultrasound carts, outreach beds, even vehicles - all funded directly through the Challenge. It’s not abstract. It’s in our community, helping real patients every week.”
Dr Tappenden agreed: “It’s not just about the equipment - it’s about connection. Many of our patients come from small communities, and travelling to Cairns for treatment can be overwhelming. Knowing there’s a program backed by riders and donors helps build trust. It shows people they matter.”
With the 2025 event fast approaching, the pair said they’re already looking forward to getting back in the saddle – and they’re hoping to see even more faces taking part in the adventure.
“Every year we finish, and every year I start planning for the next one,” Dr Potter said.
“It’s exhausting - but it’s incredibly meaningful. That moment at the finish line, hearing how much has been raised and knowing what it will fund - that stays with you.”
2025 QSuper Cardiac Challenge
The 19th QSuper Cardiac Challenge will take place from 20-22 September, with riders covering the scenic 333-kilometre stretch between Cairns and Cooktown. The event welcomes participants of all experience levels, with structured pace groups and full support along the route.
