You’re training hard. You’ve got your swim, bike and run sessions scheduled in, maybe even some strength training. But if your nutrition isn’t dialled in, you could be flushing all that hard work down the drain.

In this post, I want to shine a light on something most triathletes never calculate: the real cost of poor nutrition. And spoiler, it’s not just a bad race day or a mid-run gut explosion. We’re talking about:

• Wasted time and energy
  
• Thousands of dollars down the drain
  
• Lost performance you didn’t even realise you had in you
  
  

Let’s lift the lid.

Obvious Costs: What You Do See

These ones hurt — and most triathletes can relate:

1. Race-Day Blow-Ups or DNFs

You’ve trained for months, only to DNF because of gut issues, dehydration, or cramping. Factor in race entry fees, travel, accommodation, gear — not to mention the emotional toll. It’s not just gutting. It’s preventable.

2. Injury from Underfueling

Think stress fractures, tendon issues, or burnout from poor recovery....

Completing an Ironman isn’t for suckers. It's something that many triathletes dream about and today, I want to share the story of one of my Triathlon Nutrition Academy athletes, Christina, whose journey to the finish line of her first Ironman is truly inspirational. 

Christina isn't a professional athlete – she's a full-time interior designer and dedicated mother who held onto her Ironman dream since her post-college days in Tucson, Arizona. Fast forward 18 years, after juggling work, family, and fitness, Christina finally decided to take the plunge into this mammoth challenge and recently completed the Texas Ironman.

While preparing for race day, Christina navigated the same challenges most of us face – demanding work schedules, family commitments and the constant juggle to fit training into an already packed life. What set her apart wasn't superhuman abilities, but rather strategic planning, a personal and professional support network and an unwavering commitment to her goal.

Her ...

You're logging endless kilometres in the pool, on the bike and in your running shoes. Your training plan is meticulous. Yet somehow, the numbers on the scale refuse to budge. If you're feeling exhausted, constantly hungry and frustrated that you’re not losing body fat despite all that training, you're not alone. This is one of the most common struggles I see as an advanced sports dietitian working with triathletes.

The truth is, you simply cannot out-train a poor diet.

There’s No One Size Fits All

Next time you're at an Ironman event, take a look at the athletes around you - they’re all different shapes and sizes. Many of them train 15+ hours a week but still struggle with body composition. The disconnect often stems from a fundamental misunderstanding of how our bodies respond to training and nutrition.

It sounds like a contradiction, but under-fuelling during heavy training doesn't lead to fat loss – it leads to compromised recovery, diminished performance and a body that clings ...

If you've ever found yourself 300 meters from the buoy on race day or struggling to maintain pace during training, there might be a high-tech solution out there for you.

No magic bullet will ever replace good old fashioned swim training, but could FORM Smart Goggles be game changer?

Or are they just a fancy new gadget, or even worse, a complete waste of money?

Today I’m joined by Brenton Ford from Effortless Swimming to give us a no BS review of the FORM Smart Goggles. These high-tech goggles provide real-time metrics displayed right before your eyes as you swim but at nearly $300, are they worth the investment? 

You might know Brenton from his popular technique videos on YouTube or his coaching programs that have helped thousands of triathletes become way more efficient swimmers. With thousands of success stories under his belt, Brenton shares his professional and practical perspective on this product. There’s no sponsorship here, so rest assured this is his honest and unbiassed r...

Let's be honest – choking down another gel at hour three on a long ride isn't anyone's idea of fun. 

If you’re done with flavour fatigue, you’ve been struggling with nasty GI issues or you’ve crawled home like a zombie after bonking mid-ride, this episode is for you.

While gels and sports nutrition products have their place, they're not the only answer to fuelling your long rides. Fuelling doesn’t have to be expensive or gut-destroying. There are loads of real food options that taste amazing and keep your energy up from start to finish. Today I’m sharing five of my go-to real food ideas for long ride fuelling.

Why Real Food Matters

When it comes to sessions longer than two or three hours, proper fuelling isn't optional—it’s essential. Without effective fuel, you're risking poor performance and compromising recovery and immunity. Consistently under-fuelling can lead to fatigue, poorer training adaptations, and even hormonal issues. Let's avoid that by being strategic about our nu...

Creatine is having a serious moment right now! From bodybuilders to busy mums, we’re all being told to jump on the creatine bandwagon to  improve our strength, muscle mass and performance.

And to sweeten the deal, creatine is now available in the form of convenient and tasty gummies 

 that claim to give us the same muscle boosting powers and benefits as the powder. 

But is that actually true?

And should everyone really be taking creatine?

What Exactly Is Creatine?

First things first—why is creatine all the rage? Found naturally in our muscles, creatine helps generate energy for those intense, short bursts of exercise. It's one of the most researched supplements for improving strength, muscle mass, and performance but not everyone needs to jump on the creatine train.  It’s not a one size fits all solution and we need to be far more strategic when it comes to supplementing with creatine.

Gummies vs. Powder

The allure of creatine gummies is pretty obvious —they’re convenient an...

Nailing your training but can't shift those stubborn kilos? Maybe you’re battling gut issues despite a dialled-in nutrition plan or even dragging yourself through sessions after a solid 8 hours sleep. 

If this sounds all too familiar, it might be that your thyroid has been flying under the radar.

As a sports dietitian, I'm seeing more triathletes pushing through these warning signs – constant fatigue, resistant weight, bloating, and mysterious gut problems – not realising there's a tiny butterfly-shaped gland in their neck calling the shots. 

Thyroid health isn’t my area of specialty so today I’m joined by Registered Dietitian and Functional Practitioner, Alisha Knicely, to talk about about how this powerful gland affects everything from your race-day performance to your Monday morning motivation.

Diagnosed with an autoimmune thyroid disease in 2017 , Alisha’s drive to understand what was happening in her body was a turning point in her career. She now specialises in Hashimoto’s an...

Do you ever wake up feeling shattered but you just make yourself train hard anyway?

I know it sounds like the thing you should do, but is that actually the best thing for your recovery, your performance and ultimately, your body?

As triathletes, we’re masters at tracking watts, pace, and heart rate but there's another metric that could revolutionise your training decisions. Enter Heart Rate Variability (HRV) – your body's daily report card on recovery and readiness. 

Today I'm getting nerdy with Daniel Roland from HRV4Training to learn how tracking your HRV can help you get the most out of your training sessions, understand your recovery and avoid burnout. And all it takes is one minute every morning.

What's HRV and Why Should You Care?

Think of HRV as your body's daily stress barometer. It measures the variation between your heartbeats, giving you a window into your nervous system's state. Low HRV? Your body's in fight-or-flight mode. High HRV? You're recovering well and ready to...

Picture this: you're a dedicated triathlete, passionate about your sport and you’ve got a chronic condition that complicates every step of your training. 

My guest today is Tony Hampton and I’ll admit, he joined Triathlon Nutrition Academy (TNA) doubting whether I could help him at all. Spoiler alert - I did.

After navigating the complexities of Type 2 diabetes for over 25 years, Tony had tried everything to lose weight and get his blood sugar under control. He experimented with all sorts of diets and training regimens, but inevitably kept crashing when he hit the 2 hour mark.

Since working together in TNA, Tony’s results have been outstanding and in this conversation, we talk about his journey to weight loss, blood sugar control and what he’s learned about fuelling his body properly as a triathlete with type 2 diabetes.

Don’t Be Scared of Carbohydrates

One of the most significant shifts in Tony’s nutrition strategy was his approach to carbohydrates. Previously, he adopted a low-...

If you're racing an Ironman this season and you don’t want to be disqualified, I’m sharing some crucial information you need to know. As of 17th of March, the Ironman rules have changed which means that your current hydration set up may now be illegal.

Ironman has introduced new race regulations that limit how much fluid you can carry and trust me, you don't want to be caught off guard by these changes. 

Nobody has time to read the massive 34-page document outlining the new guidelines so today I’m breaking down exactly what the new rules mean for you. I’m sharing ways to tweak your hydration strategy and how to avoid penalties while still staying properly hydrated and fueled for peak performance.

Why the New Hydration Rules?

The new limits on how much and where you can carry fluids on your bike are grounded in safety concerns. Excess weight, especially up front, can mess with your bike handling. So, by standardising hydration setups, Ironman aims to promote fair play and improve ri...
