Building Nutrition Systems in Elite Sport

Richard Graves welcomes Dr James Morehen back to the Science for Sport podcast for a practical conversation on what it really takes to work in elite performance nutrition.

James reflects on his journey from Liverpool John Moores University to rugby league, England football, Premiership rugby, international rugby, and his current work with England Rugby. But this episode is less about the polished version of elite sport, and more about the details that actually make performance environments work.

From gaining experience as a student, to building a trusted network, to solving problems on tour before they affect the athletes, James gives a clear view of the craft behind applied performance nutrition. He explains why degrees matter, but why they are only part of the picture, and why students and early-career practitioners need to get into clubs, support research, present to athletes, make mistakes, and learn from them.

James also shares examples from inside elite sport, including heat strategies, travel logistics, hydration planning, making weight for combat athletes, and the hidden operational details that can decide whether a practitioner is adding real value or simply reacting under pressure.

This is a valuable episode for sports nutritionists, sports scientists, S&C coaches, performance directors, students, and anyone interested in the reality of working behind the scenes in high-performance sport.

In this episode you will learn

• Why academic knowledge is essential, but not enough on its own
• How students can build meaningful experience while still at university
• Why volunteering, research participation, and applied placements can separate candidates in a crowded field
• What James looks for when interviewing or mentoring young practitioners
• How to build a professional network that genuinely improves your practice
• Why elite sport often comes down to simple details done exceptionally well
• How practitioners use networks to check, challenge, and improve strategies
• What travel, heat, hydration, and logistics look like inside international rugby
• Why mentorship matters at every stage of a practitioner’s career
• How James is now helping clubs and practitioners develop better nutrition systems
