Juggling training, nutrition, and day-to-day life can be a challenge. But throw in the complexities of Type 1 Diabetes, and it’s a whole new ball game. In this special episode to coincide with World Diabetes Day, I'm joined by co-founder of Enhance-d and former head of research at Team Novo Nordisk, Sam Scott. Sam gives us a peek into the world of diabetes management for the endurance athlete. We’ll discuss what Type 1 diabetes actually is, how it’s managed, the impact of exercise, and the innovations in devices and data management that are making life a little easier to make this all work.

There’s been a lack of clear guidelines around how much sodium to take before, during and after exercise, to optimise health and performance. That created a vacuum, which anyone with a vested interest was more than happy to fill with suggestions. But we’re now getting to the stage where we can make some more specific, quantifiable recommendations about sodium for endurance athletes, before, during and after exercise. I had the privilege of being invited to put these recommendations together, so in this episode, I’ll walk you through them.     Timestamps: 02:37 - Do athletes need more sodium on a day-to-day basis? 14:42 - Sodium before exercise 25:25 - Sodium during exercise 44:32 - Sodium after exercise 49:28 - TLDL: Summary 52:13 - Unanswered questions   Read the research paper (open access): McCubbin AJ.

There seems to be two types of endurance athletes - those who are always getting sick when their training volume increases, and those who don’t. But why? In this episode we investigate the evidence around nutrition, the immune system, and illness in athletes, and come to a conclusion of what you can do to prevent getting sick during those hard training blocks, and bounce back quickly when illness does strike.   Fueling Endurance eBook | T -12 Race Nutrition Course | Practitioner Resources The Fueling Endurance eBook contains answers to 49 of the most common nutrition questions that runners, cyclists and triathletes ask, and contains insights, tips, and quotes from experts and athletes.  The T -12 self-guided course will help prepare you for your next event, with online tools, guides, information and instructions to take you through the 12 weeks leading up to race day.

Fish oil, or omega-3 supplements, are one of the most widely used supplement among the general population. But there's also been suggestions of specific benefits for athletes.  So what exactly are omega 3’s? What do they do in the body? What foods and supplements do they come from, and most importantly, do the benefits live up to the marketing hype when it comes to health and performance?   Studies/Websites mentioned: AIS Sports Supplements Framework - Fish Oil (Group B): https://www.ausport.gov.au/ais/nutrition/supplements/group_b/other/fish-oils    Fueling Endurance eBook | T -12 Race Nutrition Course | Practitioner Resources The Fueling Endurance eBook contains answers to 49 of the most common nutrition questions that runners, cyclists and triathletes ask, and contains insights, tips, and quotes from experts and athletes.  The T -12 self-guided course will help prepare you for your next event, with online tools, guides, information and instructions to take you through the 12 weeks leading up to race day.

If you’ve ridden a bike or run more than an hour or so in your life, you’ve probably considered the composition of what you’re drinking during those efforts. But what actually makes a good sports drink? Is it taste, carbs, electrolytes, osmolality, colouring, or all of the above? And is there actually an optimal drink mix that we should be looking for?

Multivitamins. About half of endurance athletes use them. There’s often an assumption that if you’re doing a lot of training, then you need a multivitamin. Or at least you should take one just in case. But is that actually true? Do runners, cyclists and triathletes actually need a multivitamin? And if so, how do you choose?

We’ve all experienced that cool mint sensation from toothpaste, mouthwash, or mint flavoured foods before. So when you’re racing in a hot environment, can this cooling sensation change how hot you feel, or even help you perform better?

Imagine being able to predict what your sweat rate is going to be at any given running pace or power output, in different weather conditions, with reasonable accuracy. Well, now you can. In this episode Prof Ollie Jay (Thermal Ergonomic Laboratory, University of Sydney), one of the brains behind this new tool, joins us to discuss how it all came together, how accurate it is, and how to best use it. Have you gone to plan your fluid needs for training or race day, but weren’t sure how much sweat you’re going to lose? Do you train in a cool environment for an event in a hot environment? Or you just don’t have the time to measure sweat losses in multiple training sessions to understand your needs?

When we think of injury prevention for runners, cyclists and triathletes we tend to focus on non-nutrition factors - training loads, shoes, biomechanics, stretching, foam rolling, strength and conditioning, and so on.

For the last few years the diabetes drug Ozempic has taken the weight loss world by storm. In this episode we’re looking at this class of weight loss drugs as they apply to runners, cyclists and triathletes. We know plenty of non-professional endurance athletes have tried, are using, or are thinking about taking these medications. So what exactly are they? Are they effective? What are the risks and side effects? And can they be compatible with endurance training?

We’ve often talked about the benefits of carbohydrate for runners, cyclists and triathletes, but for many people there’s an underlying concern - does eating all those carbs increase the risk of developing diabetes or heart disease? It’s certainly a common message that’s pushed online in some circles, but is this really the case? In this episode I speak to diabetes researcher and clinical dietitian Dr Nicola Guess from the University of Oxford, who has often been asked this exact question by concerned runners, cyclists and triathletes. We break down what science tells us about the underlying cause of diabetes, how carbohydrate, exercise and body composition fit into the picture, whether high carb diets are a risk factor for chronic disease in their own right, and whether the approach should be different based on the level of training and fitness, age, family history, and existing health conditions.   Podcast Guest: Dr Nicola Guess - University of Oxford and private practice clinical dietitian   Nicola's online presence: Instagram: @dr.nicola.guess Blog/Substack: drguess.substack.com   Diabetes risk calculators mentioned: AUSDRISK Calculator (Australia): https://www.diabetesaustralia.com.au/risk-calculator/ Diabetes UK: https://riskscore.diabetes.org.uk/start American Diabetes Association Risk Test: https://diabetes.org/diabetes-risk-test   Fuelin: This episode is supported by Fuelin, the world's first training-based nutrition app. It syncs with your training plan (in TrainingPeaks, Final Surge, and TriDot or Run Dot) and creates a personalised nutrition plan, built around your training schedule and tailored to your goals.

It's the 4th birthday of the podcast! And like each previous year, we’re going to look back and provide a brief summary of every question we’ve answered on the podcast in the past year, from “How do I work out my calorie needs for training?” to “Does pickle juice actually work?”, and “What do I do when my race nutrition plan falls apart?”.

Over the last two episodes we’ve been discussing the ‘high carb trend’ - taking in very large amounts of carbohydrate during exercise. Today we’re looking at this topic through the lens of the road marathon, an event where access to your own nutrition products is limited. In this episode I speak to marathon runner, running coach and co-host of the Inside Running Podcast, Brady Threlfall. Brady’s set a new personal best in the marathon this year, and that race included these higher carb amounts. We get his perspective on how higher carb intakes have made their way into marathon running, how he achieves this in training and on race day, and whether he feels it’s been beneficial for him and the athletes he coaches.   Podcast Guest - Brady Threlfall Instagram: @bradytrell Brady's Podcast - Inside Running Podcast Coaching - Run2PB Coaching   Fuelin: This episode is supported by Fuelin, the world's first training-based nutrition app. It syncs with your training plan (in TrainingPeaks, Final Surge, and TriDot or Run Dot) and creates a personalised nutrition plan, built around your training schedule and tailored to your goals.
