Welcome to the Triathlon Nutrition Academy Podcast! Brought to you by Advanced Sports Dietitian, Taryn Richardson. Listen as I break down the latest science to give you practical, easy to digest strategies to transform yourself into a Supercharged Triathlete! You have so much untapped potential...and I want to help you unlock that with the power of nutrition.

Skin Folds - What are they? Why you should be doing them?

You can get away with a fuelling gap over five hours. You cannot get away with it over 13.

Stepping up from 70.3 to Ironman is the exact moment most triathletes work out that their fuelling needs attention. Julie Whitton is 13 weeks out from Ironman Western Australia, her first full distance race after a decade of racing halves. She is a paramedic with New South Wales Ambulance, she has been a shift worker for 21 years, and she trains off a nine day roster that changes constantly. In this episode she takes Taryn through exactly what she has had to upgrade to get to that start line, and where the gaps showed up once the hours went up.

This is not a first Ironman story. This is the step up story, for the triathlete who already races 70.3 well and assumes that skill carries over.

 

IN THIS EPISODE
What changes in your bike and run fuelling numbers when a race goes from five hours to 13 hours
Why a small hourly shortfall you got away with at 70.3 compounds into a walk at full distance
The shift from liquid fuel to solid food on long rides, and the trap of swapping over too fast
How to gut train on gels without hitting flavour fatigue weeks before race day
What Julie was doing at 70.3 that stopped working the moment the volume climbed
Why she moved her recovery from 90 percent to 100 percent, and what that changed in her week
Fuelling your body for what you want it to do rather than for how you want it to look

 

TIMESTAMPS

04:37  Training for Ironman around shift work
07:12  Bike fuelling from 70 to 80 grams
13:25  Run fuelling and flavour fatigue
17:35  What stopped working at full distance
23:35  Fuelling for performance not appearance

 

ABOUT JULIE WHITTON

Julie (Jules) Whitton is an age group triathlete and a paramedic with New South Wales Ambulance, where she has worked shift work for 21 years. She has been a Triathlon Nutrition Academy athlete since January 2023 and is now part of the Supercharged Squad. After a decade racing 70.3, she is stepping up to full distance at Ironman Western Australia on 6 December 2026. Julie was last on the show in Episode 119, Juggling Shift Work and Triathlon.

 

If you have a couple of halves behind you and a full quietly sitting on your list, the athletes who come unstuck are almost always the ones trying to learn how to fuel and how to train for 226 kilometres at the same time. Do one of those things first.

How to Fuel an Ironman When You've Only Ever Raced 70.3

Are you paying up to $5.20 a gel because that is what they hand out on course?

Maurten, Precision Fuel and Hydration and SIS Beta Fuel are the three gels I get asked about more than any others. So I put them side by side and worked out what is actually in the packet, what each one costs you per 100 grams of carbohydrate, and whether that price gap buys you anything at all. No brand has paid me a cent to talk about them. I am Switzerland when it comes to sports nutrition products.

One of these gels costs roughly two thirds more than another for the exact same gram of carbohydrate. Whether that is money well spent comes down to three things most triathletes have never been taught to look for.

 

WHAT YOU WILL TAKE AWAY
What is actually inside each gel: carbohydrate, sodium, calories, caffeine and the main ingredients
What it costs to fuel at 90 grams of carbohydrate an hour on each brand, in both Aussie and US dollars
What the glucose to fructose ratio means in plain English, and the carbohydrate rate you need to be hitting before it matters to you
Whether the hydrogel does what the marketing implies it does
Which gel makes sense for Sprint, Olympic, 70.3 and full distance racing
How to read a sports nutrition label so you are not at the mercy of whoever has the biggest marketing budget

Maurten vs Precision vs SIS Beta Fuel: A Triathlon Dietitian's Verdict

Everywhere you look, someone is telling you to eat more protein. If you are over 45 and your power is going backwards, more protein is not the fix you have been promised. Back in January the US dietary guidelines roughly doubled their protein recommendation, and that was overdue. But guidelines written for a sedentary population are a very different thing to guidelines for an athlete training 10 to 15 hours a week. Something real does change in your muscles as you get older, and the research on masters triathletes makes for uncomfortable reading. What it does not show is that eating more protein fixes it. In this episode I take you through what is actually happening in ageing muscle, what happened when researchers doubled the protein after a muscle damaging session, and the 5 protein levers to pull instead of just reaching for more. 

WHAT YOU WILL TAKE AWAY 

• What anabolic resistance is in plain English, and why the rules changed at about 35 without anybody sending you the memo

• Inside the Australian study that compared masters triathletes with younger ones, and what happened to their muscle repair and their cycling time trials

• What doubling the post exercise protein dose actually bought masters triathletes, and what it did not • Why your total protein intake stops paying you back once you are in a reasonable range

• The 5 protein levers, and why most triathletes only ever pull number 5

• Why your breakfast is almost certainly the weak link in your day

• Why the same mistake is happening right now with carbohydrate
