He Was Scared to Run 5km. Now He’s a 100-Mile Finisher | #18 - Jason Menzies

Show Notes

Jason and I properly met on the start line of the Scenic Rim 100 — a brutal 100-mile race through South East Queensland that would become his first attempt at the distance. But Jason’s path to that start line had another layer. Three years earlier, just as he was getting into running, he was diagnosed with Type 1 diabetes. Suddenly running wasn’t as simple as heading out the door. Insulin, blood glucose, fuelling and the very real risk of a hypo all had to be considered. Rather than allowing the diagnosis to take running away from him, Jason used it as a reason to keep pushing. In this episode we unpack how he rebuilt his confidence, progressed from 50km to 100km and eventually 100 miles — while still learning how his body responds to diabetes throughout training and racing. Then we get properly stuck into Scenic Rim. A CGM that stopped working early in the race, blood glucose dropping dangerously low, running out of water, stomach issues, completing roughly 85% of the race alone and eventually reaching the Loop of Doom genuinely considering whether it was time to pull the pin. Sometimes all it takes is pumpkin soup and a few good volunteers to completely change a race. We also chat about the training that got him there, what he’d change next time, why Type 1 diabetes may have actually become part of what drives him towards harder challenges, and why he’s already signed up for his first Backyard Ultra. A great conversation about ultrarunning, problem solving and refusing to let circumstances decide what you’re capable of.

What does it take to win a 100-mile ultra when life won't allow you to train the way you used to? Just 13 months postpartum, Meg Bullen (née Coffey) won the 2025 Ultra-Trail Australia 100 Miler. With disrupted sleep, family responsibilities and training weeks that looked nothing like the 20-hour blocks she once completed, Meg had to rethink her approach to preparing for one of Australia's biggest ultras. In this episode, we explore how she adapted her training through more purposeful intensity, creative hill sessions, running with a pram and prioritising recovery. We unpack her unexpected UTA victory, the mental side of racing competitively and how motherhood has changed her motivations without diminishing her ambitions. We also revisit her incredible Delirious West 200 Miler victory, including getting lost in the bush and triggering an emergency rescue, and discuss her approach to strength training, injury management and longevity in the sport as both a physiotherapist and an accomplished ultra runner. It's a conversation about balancing ambition with reality, learning to adapt and recognising that the perfect preparation isn't always possible.

How often do we set ourselves ambitious running goals without considering whether our lives can actually support the training required to achieve them? After running a lifetime mile PB of 5:42 during my current speed phase, I've been reflecting on something that goes well beyond pace, volume and performance: creating the right environment for success. In this solo episode, I unpack the relationship between our goals, values and the sacrifices we're willing to make to pursue them. We explore why comparing your training to elite runners can be counterproductive, how I've restructured my own week to balance family, business and running, and why accepting your current circumstances doesn't mean settling for less. I also reflect on my contrasting 100-mile experiences, what my conversation with Simon Cochrane taught me about the value of long-term consistency, and why raising your training floor is often more important than chasing huge short-term improvements. Whether you're preparing for your first ultra or trying to maximise the training time you already have, this episode is about appreciating how far you've come, getting realistic about where you want to go, and identifying the next logical step.

Backyard Ultra is changing and Dead Cow Gully is about to become part of something much bigger. In this episode I sit down with Tim Walsh, founder and race director of Dead Cow Gully, to unpack the newly announced partnership with Last Soul Ultra and what it could mean for the future of backyard running in Australia and around the world. We talk about how Tim built Dead Cow into one of the most recognisable Backyard Ultras in the world, why Last Soul's approach to livestreaming and social media could fundamentally change the sport, and the challenge of growing an event without losing the authenticity that made it special in the first place. We also explore the bigger questions facing Backyard Ultra as it grows. From professional athletes and prize money to drug testing, commercialisation and whether the format could eventually find its way onto major streaming platforms. Backyard Ultra has always been beautifully simple: 6.7km. Every hour. Until one person remains. But as audiences, money, production and global interest grow, that simplicity is about to be tested.

My race calendar is winding down, but October has given me plenty to think about. I start with two stories close to home: my wife, Mahli’s month-long step challenge and a client whose trail marathon lead-up went completely off plan. It left me asking "what are we capable of when training and race day don’t look the way we expected?" Then there are lactate gels. They’re starting to appear in endurance sport, and I found a study that made me wonder whether they could have a place in ultrarunning. But there’s a catch in how the research was done. Plus, a question about longer races that I can’t stop thinking about. I unpack the idea, the unknowns and the experiment I’m tempted to try myself. I also get into the adidas super shoes making headlines after Berlin, plus a shoe concept that could change how it feels during a race. How far could shoe technology go before we have to rethink what belongs on a start line? And with UTMB changing its qualification route while details for age-group runners are still to come, I ask what this could mean for the people who help make the sport what it is.

Simon Cochrane has built one hell of an endurance résumé. But what stood out to me in this conversation wasn’t the size of the achievements — it was how simple Simon makes the process sound. After 15+ years in endurance sport, Simon has developed an incredible ability to understand what his body can handle, when to push, when to back off, and how to keep stacking productive training year after year. This ended up being a proper coach-to-coach conversation about building an enormous aerobic engine without obsessing over run mileage, learning through failure, fueling huge training loads, staying composed when races get ugly, and why the fundamentals still outperform most of the shiny stuff we get sold. Simon’s a great example of what can happen when you stay curious, train consistently and give yourself enough years to find out what you’re actually capable of.
