Triathlon Nutrition Academy

Matthew Hauser: Becoming a World Champion Triathlete

What do a rookie, a masters athlete and a seasoned racer all have in common? 

They nailed their nutrition strategy - and the results speak for themselves.

In this episode, Taryn sits down with three very different athletes from the Triathlon Nutrition Academy - Jo, Kelly and Erin - to unpack the surprising impact of getting their fuelling right. Each had their own goals, challenges and training loads, but all saw game-changing results after implementing the same evidence-based framework.

If you’ve ever wondered whether nutrition could be your missing link, this episode will show you what’s possible when you get it right.

Timestamps & Highlights
 00:00 – Intro: The effort gap between training and fuelling
01:35 – Meet Jo, Kelly & Erin: Different athletes, same frustration
06:00 – Why nutrition felt confusing (and what they used to get wrong)
14:00 – The turning point: How each athlete transformed their approach
22:00 – The race-day difference: Confidence, control and results
37:00 – Real-world results: Massive time gains, body comp shifts & more
51:00 – Advice for triathletes: When (and why) to start focusing on nutrition
58:00 – Final takeaways: What they'd tell their pre-TNA selves

Key Takeaways
Why fasted training, bonking and confusing advice were holding them back
How a repeatable fuelling strategy boosted their performance and recovery
The underrated power of recovery nutrition (yep, everyone was doing it wrong)
The value of education: apps are fine, but understanding is power
Massive PBs, sustained weight loss, strength gains and podium finishes

Three Triathletes. One Strategy. Ridiculous Results

How a Full-Time ER Doctor Shaved 65 Minutes Off His Ironman PB

🎧 “You don’t have to sacrifice your health or performance when life gets busy - if you get your nutrition right.”

In this episode, I’m joined by TNA alum and emergency room physician, Edward Walsh, who proves that even the busiest triathletes can thrive when they fuel smart.

Despite working irregular hours in one of the most demanding medical fields, Edward has dropped 12kg, avoided injury, and slashed 65 minutes off his Ironman time, finishing Ironman Maryland in 11:28. He backed it up with a 5-hour 70.3 at Wilmington just weeks later.

We dive into:


How Edward manages long course triathlon training around 12-hour night shifts


The game-changing fuelling strategies that helped him stop bonking, drop body fat and set PBs


His biggest mistakes before joining the Triathlon Nutrition Academy - and what he does differently now


Why recovery nutrition was the turning point for performance and body composition


The nerdy fuelling tactics he now teaches his own patients

Whether you're juggling a chaotic schedule or struggling to match your effort with results, this episode is for you.

⏱ Timestamps:
0:00 – Meet Ed: Emergency doc, triathlete, time juggler
6:30 – From walk-run 5K to Ironman finisher
10:00 – Pre-TNA nutrition mistakes (bonking, weight gain, low energy)
13:40 – The mindset shift: from dieting to fuelling
16:30 – Race results unlocked by fuelling properly
20:30 – Practical fuelling hacks: from recovery meals to bottles on the bike
26:00 – How he fits TNA around a crazy schedule
32:00 – The culture shift: preaching nutrition in the ER
36:30 – Ed’s advice for other busy triathletes

You Won’t Believe How Edward Dropped 12kg and Took 65 Minutes Off His Ironman

Are you outsourcing your nutrition to an app or ChatGPT and hoping it just works? Here’s why that could be a massive mistake...

In this episode, I unpack the shiny trap of using AI tools and nutrition apps to guide your fuelling strategy. Sure, they’re convenient, look polished and promise quick wins – but are they really working for you?

Triathletes aren’t 80% people – and near enough with nutrition just doesn’t cut it when you’re training for three sports. If you’ve ever second guessed whether your plan is right or felt unsure when your energy’s low or recovery is off – this episode is for you.

Learn how to stop blindly following what an app tells you to eat and start building true confidence in your nutrition.

In this episode, I cover:

⏱ 00:00 – Why this episode might make you uncomfortable (and that’s a good thing!)
⏱ 01:20 – Where AI and apps get you halfway – and where they fall short
⏱ 02:50 – The human factor AI can’t replicate: sleep, stress, life
⏱ 04:00 – What real confidence in your nutrition actually looks like
⏱ 09:20 – A real athlete case study: when a flashy AI plan under-fuelled a seasoned triathlete
⏱ 13:40 – The danger of normalising under-fuelling and feeling flat
⏱ 17:30 – Why education, not automation, is the real game-changer
⏱ 19:45 – How to use AI as a tool – not a crutch
⏱ 22:00 – The real reason the Triathlon Nutrition Academy exists

Want to stop second guessing your nutrition?
