Episode 93 - Can menthol improve my performance in the heat? | Dr Erica Gavel-Pinos
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? And is there any downside to this? Or like a lot of things in science, is it maybe not that simple?

Episode 92 - Can I trust AI with my sports nutrition questions?
Artificial intelligence is quickly becoming many people's go-to for answers to their sports nutrition questions. It has a knack of taking your question, exactly as you asked it, and providing what seems like the perfectly relevant answer. But is AI really providing the answers you’re looking for? Is it telling the truth? And if not, how can you tell?

Episode 91 - Can I predict my sweat losses without actually measuring them? | Prof. Ollie Jay
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? This is the podcast for you.

One of the most common bits advice you see for runners, cyclists, and triathletes is to avoid gluten, either on a daily basis, or in the days leading up to competition. So where does this advice come from? Is it effective? And most importantly, is there a better approach?

Episode 89 - Does nutrition have a role to play in injury prevention? | Erin Colebatch
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. But what about nutrition - does it have a role to play too? We're joined by sports dietitian and ultra-runner Erin Colebatch, whose current research seeks to answer this question.

Episode 88 - Can GLP-1 agonists work for runners, cyclists and triathletes?
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?
Notes: This episode is a dietitian's perspective on weight loss medication and its role in nutrition for athletic performance. It does not constitute medical advice. This episode contains discussions about body image, injectable drug use, disordered eating and eating disorders.

Episode 86 - How does endurance sports nutrition evolve?
On today’s episode we’re dissecting how sports nutrition evolves over time. The diets, the foods, the supplements, and the attitudes to health, body composition and performance. How and why does this stuff change over time, and can that tell us anything about the future? As much as we’d like to think things are always evolving for the better based on new scientific research and insights, that’s definitely not always the case.

Episode 85 - Are high carb diets a health concern for athletes? | Dr Nicola Guess
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.
