How to Fuel Your First Ironman and Actually Enjoy It with Lily Godding

Two of the best triathletes on the planet came undone in the Kona heat in back-to-back years, so how do you fuel a hot race without falling apart on the run? After two decades of working with triathletes, I can tell you that most hot races are won or lost before the gun even goes off. As an age-grouper you’re out on course for hours longer than the pros, in the hottest part of the day, often on a race nutrition plan you built and tested through winter. I break down what the heat actually does to your body, why falling apart in a hot race comes down to much more than toughness and what should change in your plan when the forecast says it’s going to be a scorcher. WHAT YOU’LL LEARN Why your body burns through stored carbohydrate faster in the heat, and why your aid stations can only top up so much The 3 ways triathletes fall apart in a hot race that look identical from the side of the road, and why they need opposite fixes Why “it’s hot, drink more” is the advice that puts age-groupers in the medical tent What heat does to your gut, and why backing off your fuel can make it worse The 4 mistakes I see over and over when the forecast is hot How one of my Academy athletes went from walking between poles at Spudman to crossing the line at the 70.3 World Championship in Nice TIMESTAMPS 00:00 Introduction 01:28 How heat changes your body's job 03:30 3 ways to fall apart in a hot race 07:03 Why your gut struggles in the heat 09:16 4 mistakes when the forecast is hot 13:08 How to prepare for a hot race STUDIES MENTIONED Almond, C.

Are you still training like you did in your 20s, going hard every session and wondering why recovery takes so much longer than it used to? This is one of the most listened-to episodes of the Triathlon Nutrition Academy podcast, back by popular demand.

Joe covers the training side and my Ep 178 on key nutrients for masters triathletes covers the nutrition side, so listen to them as a pair.

Why is your triathlon nutrition strategy still not working when you already know what to do? I asked the triathletes who just finished my Triathlon Fuel Camp what they had spent money on to improve their performance. 70% had paid for a bike fit, 66% had a coach and 50% had bought a power meter and faster wheels. Only 20% had ever invested in a dietitian or nutritionist, and 57% told me they were winging their nutrition. These are smart, driven athletes with more information at their fingertips than any triathlete in history. So why is it still not working? IN THIS EPISODE, YOU WILL LEARN: Why more information is not what is missing from your nutrition What a strategy specific to you is actually built on (and why generic advice never holds for long) The 3 ways triathletes try to build a nutrition strategy, and the only one that lasts your whole racing life The 3 questions that keep triathletes on the precipice of dialling in their nutrition for years How Kelly, Steve and Julia from the Triathlon Nutrition Academy finally got off the fence TIMESTAMPS 02:02 Why your triathlon nutrition strategy isn't working 10:15 3 questions holding triathletes back EPISODES MENTIONED Episode 235 with Julia Episode 237 on why DIY nutrition is not working Episode 259 with Kelly and the TNA crew at the 70.3 World Championship in Nice Episode 261 with Steve, Curt and Jade READY FOR A STRATEGY THAT IS SPECIFIC TO YOU?

If you have heard about the Triathlon Nutrition Academy and wondered what it actually is, this is your answer in under 10 minutes. You already have a training system. You have a coach or a program, a week of sessions you love to turn green and the discipline to follow it. What most triathletes don't have is a nutrition system that is just as organised, and that is exactly what you walk out of TNA with. I take you through how my 9-month program works, the 4 things that change when your nutrition is dialled in and who it is genuinely for (and who it is not for). WHAT YOU WILL TAKE AWAY How TNA is built so you actually put it into practice, rather than buying something and never using it Why being able to function like an adult after a long ride is one of my KPIs How Stephen went from nearly quitting triathlon over cramps to taking 64 minutes off his 70.3 time, and why magnesium was never the fix How the program fits into 1 to 2 hours a week, whatever your time zone and however full your life is What changes when you become the expert on you, from every gel to every supplement ad in your feed What Kelly Estes, 4 years in, says happens by the end Who TNA is for, from your very first season to your 30th, and who should not join right now TIMESTAMPS 03:00 What changes when your nutrition is dialled in 07:16 Is this triathlon nutrition program right for you ATHLETE STORIES MENTIONED Stephen Duquette and the TNA athletes who raced the 70.3 World Championship in Nice: Episode 259 Jade, Curt and Steve, 9 months after joining TNA: Episode 261 If you want to see everything that is included, head to dietitianapproved.com/academy.

What happens when you eat 1,000 more calories a day? For Curt, a 54 year old triathlete from Texas, it meant losing 8kg, ditching the daily nap and finally making it through a training day without bonking. That is not a typo, and it is not a fluke. Nine months ago, three brand new Triathlon Nutrition Academy athletes came on the show a few weeks into the program to share what it is really like on the inside. Now Curt, Jade and Steve have finished all three phases and they are back. Three different athletes, three different decades of life and three very different starting points: a 39 year old mum of three from WA in her second Ironman build, a scientist from Texas who watched from the sidelines for 4 years while his mate got faster and a 71 year old from San Diego with more than 300 races behind him and no formal nutrition education until now. WHAT YOU WILL TAKE AWAY Why Curt lost 8kg while going from around 2,000 to closer to 3,000 calories a day, and why underfuelling was the thing keeping the body fat on The one change that eliminated Curt's post-workout naps and gave him back at least an hour a day How Jade went from years of fasted sessions to fuelling every session, and what changed when she hit 90g of carbs an hour on the bike Why Steve calls nutrition free speed after 30 years of hand waving it, and how a race week plan changed 5 national championship races in 3 days What separating fluid from fuel does to a race day plan The benefits nobody expected outside triathlon, from a happier marriage to more beach days and a kid who packs his mum's long run fuel What all three would say to the version of themselves sitting on the fence 9 months ago Nutrition is not something you fix in a week, and it is not something you fix for life by collecting free nuggets from AI, YouTube or podcasts. It is something you learn, practise and make your own. That is exactly what the Triathlon Nutrition Academy is built for: 9 months learning how to fuel your body for your own training, with me and a group of legends like Curt, Jade and Steve beside you. Doors to the Triathlon Nutrition Academy are open right now. Join the October cohort here before doors close on Saturday 10 October.
