Triathlon Nutrition Academy

Ironman has changed its on-course hydration globally. Sounds simple. It’s not.
All Ironman-branded events have now moved to PH1000 for hydration and Maurten for carbohydrate fuelling, separating fluids and carbs completely. If you’ve relied on sports drink to do both jobs, this shift has major implications for your race nutrition plan.
In this solo episode, I break down exactly what’s changed, how much sodium you’re actually getting per bottle and how to decide whether this setup works for your individual sweat rate, sodium losses and fuelling preferences.
Because hydration and sodium are never one-size-fits-all. And winging it at 70.3 or full distance is how you end up walking the marathon.
Chapters & Highlights:
00:00 - Why this Ironman change matters02:15 - What’s actually changed on course05:30 - PH1000 explained: sodium without carbs08:10 - How to calculate sodium per bottle11:45 - Will this setup work for you?14:20 - What if you prefer to drink your carbs?16:00 - Why practising in training is non-negotiable18:00 - How to build a race plan that actually works
Key Takeaways:
PH1000 provides 1000mg sodium per litre and zero carbohydrate

Carbohydrates now come separately via Maurten gels and solids

Your sweat rate and sodium losses determine whether this works for you

You may need to be more self-sufficient on race day

Testing your full race setup in training is essential

Hydration isn’t about what’s on course. It’s about knowing your body and executing with confidence.

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.

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
