    How to Fuel Your First Ironman and Actually Enjoy It with Lily Godding
    Jun 18 2026
    What does it actually take to finish your first Ironman at 22 years old - and cross that finish line with a smile? Lily Godding is a TNA athlete, a rugby rep player and a chef who had never raced a triathlon three years ago. On the weekend, she crossed the finish line of Ironman Cairns 140.6 in 13 hours, 21 minutes and 54 seconds. In this episode, Taryn sits down with Lily just days after the race to talk about what it took to get there — the brutal washing-machine swim, the six-and-a-half-hour bike leg, and the moment on the run where Lily quietly reminded herself: I can do hard things.

  • Five Habits of Triathletes Who Reach the Start Line Ready to Race

    Five Habits of Triathletes Who Reach the Start Line Ready to Race
    Jun 11 2026

    Are you actually going to hit the start line ready - or are you going to arrive having done all the training but undone the work in race week?

    Taryn is recording this one live from Cairns, where the TNA crew has flown in from all over the world to race the 70.3 and Ironman. Every single one of these athletes had their race nutrition dialled in months ago. Not this week. Not over last night's bowl of pasta. Months ago.

    In this episode, Taryn shares the five habits that separate triathletes who arrive on race morning topped up, adapted and confident from those who roll up to the start line under-fuelled before the gun has even gone off.

    What you'll learn:

    • Why race week is not the time to train harder or eat less - and what the taper trap actually does to your fuelling
    • How recovery nutrition session by session is what makes the hard work stick
    • Why rehearsing your race fuelling on long sessions is non-negotiable (and what happens when you wing it on race day)
    • The one habit that quietly takes more athletes out of their A-race than any fuelling mistake out on course
    • How to carb load properly - because no, it is not a giant bowl of pasta the night before

    TIMESTAMPS

    00:00 Introduction — Live from Cairns

    06:37 Habit 1 — Bank the adaptations and protect the taper

    09:11 Habit 2 — Recover from every session

    12:38 Habit 3 — Rehearse race fuelling on long sessions

    15:02 Habit 4 — Protect your immune system

    17:48 Habit 5 — Plan and practise your carb load

    20:14 Race Day Pack List

    21:40 Summary and close

    RESOURCES MENTIONED

    Recovery Accelerator - the exact framework Taryn teaches TNA athletes for what to eat after every training session and every race (the four R's, when to eat, what to eat and when to prioritise it). You can get through it all in one trainer session or one long run

  • Does Hydrogen Water Actually Work for Triathlon Recovery?

    Does Hydrogen Water Actually Work for Triathlon Recovery?
    Jun 4 2026
    Hydrogen water is all over your feed right now. Tablets, bottles, little machines bubbling away on the kitchen bench, all promising less soreness, faster bounce-back and recovery at the cellular level. But does it actually do anything for you as a triathlete, or are you about to drop sixty bucks on fizzy water? In this episode I give you my honest, no-BS breakdown on hydrogen water. What it actually is, what the research genuinely says about recovery and performance, and whether it earns a spot in your toolbox. Then I run the actual numbers on what it costs to replicate the research dose (you might want to sit down for that part) and weigh it up against where your money is truly best spent. WHAT YOU'LL LEARN • What hydrogen water actually is, and why the marketing sounds far more exotic than the science • What the research really shows on recovery, soreness and performance • Why mopping up every free radical from training might quietly blunt the adaptations you work so hard for • The real cost of replicating the research dose, run line by line • The two-dollar recovery option that ticks every box hydrogen water misses TIMESTAMPS 00:00 The fizzy tablet moment 01:39 What this episode covers 04:20 What hydrogen water actually is 05:45 The theory: mitochondria and selective antioxidants 08:38 What the research shows (the fin swimmer study) 12:45 The bigger systematic reviews 15:00 Why you don't want to mop up every free radical 17:50 The honest verdict on the evidence 20:11 The real cost, run line by line 23:05 The two-dollar recovery smoothie comparison 25:53 The athlete I see all the time 28:24 Red light therapy: same pitch, better evidence 30:32 Pulling it all together 33:14 Where to start instead STUDIES MENTIONED Li, Y., Bing, R., Liu, M., Shang, Z., Huang, Y., Zhou, K., Bao, D., & Zhou, J.

  • The 3 Recovery Nutrition Mistakes Triathletes Make (And How to Fix Them)

    The 3 Recovery Nutrition Mistakes Triathletes Make (And How to Fix Them)
    May 28 2026

    You’re doing the training. You’re showing up consistently. But if your legs constantly feel heavy, your energy crashes every afternoon and you can’t seem to bounce back between sessions, your recovery nutrition could be the missing piece.

    In this episode, Advanced Sports Dietitian and Triathlon Nutrition Specialist Taryn Richardson breaks down the three biggest recovery nutrition mistakes triathletes make and explains exactly how to fix them.

    Because recovery is where adaptation actually happens.

    Recovery Accelerator Program

    Taryn dives into:

    • Why your post-training nutrition window matters more than you think
    • The common protein mistake endurance athletes make
    • Why carbohydrate is critical for triathlon recovery
    • The signs your recovery nutrition is failing you
    • How poor recovery impacts performance, body composition and immunity
    • What proper recovery should actually feel like
    • Practical strategies busy triathletes can use to recover properly even with work, kids and life chaos

    If you’re training hard but still feeling flat, sore or permanently fatigued, this episode will help you connect the dots.

    In This Episode:

    [00:00] Why recovery nutrition gets pushed aside for busy triathletes

    [04:20] What actually happens physiologically after training

    [05:45] The research on delayed recovery nutrition and glycogen restoration

    [08:50] Why so many triathletes get recovery wrong

    [09:40] Mistake #1: Having no recovery nutrition plan

    [11:55] Mistake #2: Focusing on protein while forgetting carbohydrate

    [13:50] Mistake #3: Poor timing

    [15:40] Signs your recovery nutrition is not working

    [17:50] What proper recovery should feel like

    [20:15] Why adaptation happens during recovery, not training

  • What Ozempic and GLP-1 Drugs Do to Your Triathlon Performance

    What Ozempic and GLP-1 Drugs Do to Your Triathlon Performance
    May 14 2026

    GLP-1 medications like Ozempic, Wegovy and Mounjaro are now firmly inside the triathlon conversation. Athletes are seeing dramatic weight loss results and wondering whether these drugs could help them perform better too.

    But what actually happens when you combine appetite-suppressing medications with the demands of swimming, riding and running for hours every week?

    In this episode, Advanced Sports Dietitian Taryn Richardson breaks down the science and practical realities of GLP-1 medications for endurance athletes. From muscle loss and gut issues to RED-S and race day fuelling disasters, this is the conversation triathletes need to hear before considering these medications.

    In this episode, you’ll learn:

    • What GLP-1 medications actually do in the body

    • Why delayed gastric emptying can become a major issue for endurance athletes

    • The surprising amount of muscle mass that can be lost during rapid weight loss

    • How GLP-1 medications may increase the risk of RED-S in triathletes

    • Why hunger and thirst cues become unreliable on these medications

    • The key nutrition strategies to protect your performance if you’re taking a GLP-1

    • How protein and resistance training can help preserve lean muscle mass

    • Which foods give you the biggest micronutrient bang for buck when appetite is low

    • Why fuelling to a schedule becomes critical during long training sessions and racing

    • What WADA’s monitoring of GLP-1 medications means for athletes moving forward

    Key Takeaways

    • Rapid weight loss can come with significant lean muscle loss if nutrition and strength training aren’t prioritised

    • Slower gastric emptying may increase the risk of gut distress during training and racing

    • Suppressed appetite can make chronic under-fuelling and RED-S much harder to detect

    • Triathletes taking GLP-1 medications need a very deliberate fuelling plan to maintain health and performance

    Timestamps

    • 00:00 – Why GLP-1 medications are suddenly everywhere in triathlon

    • 01:47 – What GLP-1 medications actually do

    • 03:00 – WADA monitoring and anti-doping implications

    • 04:09 – The muscle mass problem triathletes need to understand

    • 06:34 – Gut function, gastric emptying and fuelling challenges

    • 08:50 – The hidden risk of RED-S and chronic under-fuelling

    • 11:13 – Practical strategies for athletes using GLP-1 medications

    • 12:35 – The most nutrient-dense foods when appetite is low

    • 14:00 – Why fuelling to a schedule matters

    • 16:00 – Final takeaways for triathletes

    If you know a triathlete currently taking Ozempic or another GLP-1 medication, send them this episode. These conversations are happening quietly in squads all over the world, and athletes deserve practical, evidence-based guidance to protect both their health and performance.

    May 7 2026
    What does it actually take to recover from surgery in half the expected time and come back stronger than ever? Australian elite triathlete Emma Jeffcoat did exactly that — and she's on the podcast to break down how. About Emma Jeffcoat Emma Jeffcoat is an Australian elite triathlete and Tokyo 2020 Olympian based on Sydney's Northern Beaches. A former surf lifesaving ironwoman and registered nurse, Emma switched to triathlon in 2015 and hasn't looked back. She is a Mixed Team Relay World Champion (2024), Australian Elite National Champion (2021) and multiple World Cup winner. Known for her powerful racing, fierce resilience and trademark smile across every finish line, Emma is now also joining the NSW Fire Brigade — all while gunning for a mixed relay gold medal at the 2028 LA Olympics. Connect with Emma: Website: emmajeffcoat.com.auInstagram: @emmajeffcoat About This Episode Emma first joined the Triathlon Nutrition Academy Podcast all the way back in Episode 91 — Life of an Elite Australian Triathlete. Three years later she is back, and what a journey it has been. Mixed Team Relay World Champion. A new career with the NSW Fire Brigade. An acute ankle reconstruction that left her surgeon speechless at the speed of her recovery. And a deeply honest account of going from a decade of amenorrhea and RED-S to running 80km weeks and racing at her absolute best. This episode is packed with gold for triathletes at every level — practical, personal and genuinely inspiring. What You Will Learn The four-pillar recovery protocol Emma used to come back eight weeks ahead of scheduleExactly which supplements she used and why (collagen, creatine, fish oil, magnesium)Why nutrition has to come first — before hyperbaric chambers or red light therapy mean anythingHow Emma manages the mental side of injury, including her work with a sports psychologistHer raw and honest account of ten years with amenorrhea, RED-S and the bone stress injuries that followedThe moment someone showed her the actual energy numbers — and everything clickedHow she went from 40km capped run weeks to 80km weeks and winning World CupsHer decision to freeze her eggs after 10 years of amenorrhea affected her AMH and fertilityThe big life plan: Fire Brigade, LA 2028 mixed relay gold and what comes after elite sport Episode Timestamps [00:00] Welcome back Emma — life update including Mixed Relay World Champs, the move back to Sydney and joining the NSW Fire Brigade[03:47] The injury: acute posterior tibialis tendon rupture and full ankle reconstruction[06:35] Milestones that blew the surgeon's mind: walking at four weeks, boot off and swimming normally by six weeks[08:51] The four recovery pillars: rest, nutrition, hyperbaric oxygen and red light therapy[10:13] Fuelling for recovery, not restriction: how Emma approached nutrition when training load dropped to near zero[12:38] Hyperbaric oxygen therapy: four sessions a week and why the surgeon called it gold standard[13:08] Red light therapy: passive, practical and something Emma will continue long-term[16:46] Staying positive through injury: the 24-hour rule, drawing a line in the sand and working with a sports psychologist[22:00] Three years of evolution: what has changed in nutrition, mindset and self-awareness[24:05] What proactive and consistent fuelling actually looks like day to day for an elite athlete[29:38] From tightrope to bridge: what adequate fuelling has done for Emma's injury resilience and training availability[32:26] Body image, social media and why Emma deleted Strava from her phone[38:03] RED-S in triathlon: the moment Emma saw her energy numbers and everything changed[46:55] Getting her period back after 10 years of amenorrhea and the compounding effect of proper fuelling[50:09] Egg freezing: making proactive decisions for fertility and life after elite sport[54:30] Balancing elite sporting goals with long-term life goals[58:08] The grand plan: Fire Brigade, LA Olympics mixed relay gold and what comes after Key Takeaways Nutrition first, always. Recovery nutrition is not about restriction. Carbs, fats and proteins all stay on board. Your body is doing serious work healing.Big rocks before sprinkles. Hyperbaric and red light therapy are powerful tools — but only once sleep and fuelling foundations are locked in.Proactive beats reactive. From booking psych appointments before she thought she would need them, to planning her nutrition before injury progressed — Emma stays ahead of problems.RED-S is rampant and reversible. Emma went from chronic bone stress injuries and 10 years without a period to running 80km weeks and winning World Champs. The difference was fuelling adequately.Honesty accelerates progress. The more open Emma was with her dietitian, physio, coach and family, the more effectively they could actually help her.
