232. Fuelling Performance: Nutrition Insights for Runners | Beck Haslam (Sports Dietitian, PhD)
Today on the Strongest Time podcast, we’re joined by Beck Haslam — sports dietitian, PhD in human physiology, and founder of Nutrient Nation — to unpack one of the most misunderstood (and under-fuelled) areas of endurance sport: nutrition.
Beck shares her journey into dietetics and sports nutrition, and explains why what you eat every day matters just as much — if not more — than what you do on race day. From pre-training fuel and carbohydrates to hydration, immune function, and fad diets, this episode is packed with practical, evidence-based advice for runners of all levels.
We discuss:
• Why nutrition is the second most important factor for race-day performance (after training)
• How to start fuelling before training — even if you “can’t eat before runs”
• Common mistakes runners make with carbs, hydration, and meal timing
• The risks of eliminating food groups and restrictive diet trends
• Under-fuelling, illness, and the link between nutrition and immune function
• Hydration and electrolyte balance for endurance athletes
Whether you’re training for your first event or deep into endurance performance, this episode will help you rethink how you fuel — not just for racing, but for long-term health and consistency.
Sound bites:
“Start small with pre-training nutrition.”
“Nutrition is the second most important factor for race day.”
“Under-fuelling increases the risk of getting sick.”
