    Beginner to Ironman in 5 months: 4 Days Out, My Final Thoughts

    With only four days until race day, I get really vulnerable about the reality of Ironman training. This isn’t a highlight reel; it’s a transparent look at the exhaustion, the ugly side of endurance prep, and the final lessons learned after five months of intense training. From the surprising reality of weight gain during prep to the emotional toll of pushing your limits, I share why I'm no longer chasing invincibility and how I'm preparing to cross the finish line. The Reality CheckReflecting on the "glamour" of Ironman training. Lesson 1: The Nutrition ParadoxWhy tracking calories and macros is about fuelling, not weight loss. Lesson 2: Gear – What You Actually NeedDifferentiating between "nice-to-haves" and essentials. A breakdown of bikes, trisuits, and why you should probably learn how to oil your own chain. Lesson 3: The Data TrapReflecting on the use (and non-use) of bike computers and indoor trainers. Why real-world experience often trumps hitting specific wattages for a first-timer. Lesson 4: Parkinson’s Law & Training StructureHow "total flexibility" led to procrastination. The importance of creating an unbreakable daily structure to reduce decision fatigue. Lesson 5: Breaking the "Invincible" MythA raw discussion on the mental and physical exhaustion of the last four months. Why crying doesn't mean weakness and how to handle it It Takes a VillageFinal thoughts on the support system—from best friends to the online community—that makes the start line possible. Key Moments: Fueling is a Science: Training 20+ hours a week doesn’t give you a free pass to eat everything in sight; it requires a calculated approach to ensure you have the energy to recover without carrying "dead weight" on the hills. Don't Over-Gadget: For your first Ironman, consistency and comfort on the bike are more important than owning every piece of high-tech data equipment. Focus on a good bike fit and basic maintenance. Structure is Freedom: Having all day to train can lead to procrastination. To avoid burnout and "decision fatigue," schedule your workouts into fixed windows (AM/PM) just like a 9-5 job. Embrace the Vulnerability: Physical training is only half the battle. Acknowledge the emotional toll and the "why" behind your race, as that mental resilience is what carries you through the final miles. You Aren't Alone: No one reaches an Ironman finish line in a vacuum. Lean on your community and acknowledge the collective effort it takes to get to the start line.

    Beginner to Ironman in 5 Months: Running Focus

    One week out from race day, I dive into the final discipline of the Ironman: The Run. After a lifetime of running for PB times and headspace, I reflect on the humbling reality of training for a marathon that starts after 180km of cycling. From the "syrup-leg" feeling of brick runs to the mental toll of losing speed to gain endurance, this episode is a candid look at the physical and psychological shift required to become an Ironman runner. Welcome to the Ironman Diaries: 1 Week to Go! My Running History: From University Half-Marathons to 3:20 Fulls. The Identity Crisis: Runner vs. Triathlete. Lesson 1: When your passion becomes a chore. Lesson 2: Letting go of the "Runner Self" and chasing new paces. Lesson 3: The Zone 2 Survival Guide (Audiobooks, Fuel, and Shoes). Lesson 4: The "Brick Run" experience (Running through syrup). The "Brick Run Banana" and fuelling for the 42.2km finish. What’s next? Weight gain, gadgets, and pre-race tears. Prioritise the Weakness: Because running was a strength, it often got the "leftover" energy after cycling sets, turning a hobby into a chore. Acknowledge this mental fatigue early. Release the Ego: You cannot compare your marathon-block paces to your Ironman-block paces. Zone 2 training builds the engine you need for the finish line, even if it feels "slow" compared to your PBs. Save Your "Demon Thoughts": Don't use up all your mental grit in training. Use podcasts and audiobooks for long Zone 2 sessions to keep your mind fresh for the "dark places" on race day. The Shoe Rotation Matters: Save the high-stack tempo shoes for specific sessions. Training in daily trainers (like the Gel Nimbus or Novablast) keeps your legs honest and prevents over-reliance on tech. The "Brick" Sensation: Expect the first few kilometers off the bike to feel like running through syrup. Higher cadences on the bike can help the transition, but nothing beats the "Brick Run Banana" for a mid-transition energy boost. @theexerciseengineer

    Beginner Triathlete to Ironman: The Swim

    In this episode, Lou breaks her four-month silence to give a "no-filter" recap of her Ironman journey so far. Transitioning from a beginner to a long-distance triathlete is no joke, and while the swim might be the shortest leg of the race, it’s proving to be the biggest mental hurdle. Lou shares her ego-bruising lessons on technique, the tools she wish she’d used sooner, and the pre-pool anxiety that almost kept her on the couch. The "Ironman Distance" reality check. The Math of a Triathlon: Why the swim is often the forgotten discipline. Lesson 1: Swallowing the ego and using swim tools (Paddles & Pull Buoys). Lesson 2: Intervals vs. Distance – Why "just swimming" isn't enough. Lesson 3: The Open Water Fear – Wetsuits, sighting, and toe-grabbing. Lesson 4: The Mental Game – Overcoming pre-swim procrastination and finding "flow." What’s coming up next (The Bike). The Power of Tools: Don't let your ego stop you from using paddles (for hand positioning/catch) and pull buoys (for hip buoyancy). They are shortcuts to better form, not "cheating." Structure Over Volume: Simply grinding out lengths is great for the soul but bad for the clock. Break sessions into intervals to maintain technique and build actual speed. The "Blue Line" Trap: Pool swimming doesn't prepare you for the variables of open water. Practice sighting and getting comfortable in a wetsuit to avoid race-day surprises like chafing or shoulder fatigue. The 60-Minute Mental Wall: Swimming is the ultimate "unplugged" sport. While the pre-swim anxiety is real, pushing through to find a flow state is where the magic happens. "I’ve never known procrastination like it... but once I’m in the pool and I find flow state, it’s the most magical thing."

  5. Why Discipline and Systems Are Your Key to Success

    Why Discipline and Systems Are Your Key to Success

    In this episode, Lou investigates the critical distinctions between motivation, discipline, and systems, emphasising why systems ultimately lead to success. She begins by redefining how we think about discipline, debunking the myth that it requires extreme toughness or willpower. Instead, Lou highlights the importance of creating an environment that makes the right choices easier. KEY TAKEAWAYS Discipline is not about being tough or having willpower; it's about creating systems that make the right choices easier. By arranging your environment and routines strategically, you can make success more accessible. Motivation can fluctuate like a phone battery and is not a dependable source for achieving goals. Instead of relying on motivation, establish systems and routines that allow you to take action consistently, regardless of how you feel. Implementing tiny, consistent actions can lead to significant results over time. Starting with manageable tasks, such as prepping one meal or committing to a short workout, can build momentum and confidence. Instead of trying to eliminate bad habits outright, replace them with healthier options. For example, swap out unhealthy snacks for nutritious ones to make the transition easier and more sustainable. Planning and structuring your life reduces decision fatigue and stress, allowing you to focus on executing your goals. By mapping out your week in advance, you can free up mental energy for the actions that matter most. BEST MOMENTS "Discipline is about making success easier than failure is." "Motivation feels amazing when it's there but it is completely unreliable." "The more structured your life is, the more freedom you actually have." "Tiny, consistent, mini actions will lead to massive changes over time." "Building discipline through the systems doesn't just change your outcome, it will actually change who you are."

  6. Running Culture & Performance Pressures With Cam Campbell

    Running Culture & Performance Pressures With Cam Campbell

    Today, Lou interviews Cam, a Sydney-based hybrid athlete and runner who is training for a sub-3:30 marathon at the New York City Marathon. They delve into the impact of culture on athletic performance, exploring the differences between fitness communities in Australia and the UK. Cam shares insights into his training regimen, which includes strength sessions and running, while balancing a full-time job. KEY TAKEAWAYS The fitness culture in Sydney is significantly more vibrant and active compared to the UK, with a larger number of people participating in running and fitness activities. This can create both motivation and pressure for individuals to perform at higher levels. It's important to set achievable goals based on personal capabilities rather than external expectations. While it's beneficial to be inspired by others, individuals should focus on their own progress and celebrate their achievements, regardless of how they compare to others. Juggling a full-time job with training requires flexibility and planning. Incorporating training sessions into daily routines, such as lunchtime workouts or adapting runs to fit social activities, can help maintain a balance between work and fitness goals. After intense training or races, allowing time for recovery is crucial. This includes taking a break to celebrate achievements and giving the body time to recuperate before starting the next training block. Proper nutrition and hydration are essential for performance. Strategies such as timing gel intake with water stations during races and maintaining a balanced diet with high protein options can help prevent issues like cramping and support overall training efforts. BEST MOMENTS "I feel like there's a lot more people that are fitter here and wanting to look after themselves. It's quite overwhelming, but it's a positive and a bit of a negative sometimes." "Running a sub-330 marathon feels like a big achievement to me, but sometimes it doesn't feel like a big achievement when you're talking to people after a race." "I think it's about setting realistic goals and trying to stick to the plan, getting the reps in and achieving those goals." "The new normal here is to be able to run a sub-three marathon, finish an Ironman. That's normal here, which is absolutely ridiculous." "I think social media definitely puts a bit of a highlight on marathons, and no one really shows the amount of work that actually goes into a marathon."
