Trent Stellingwerff, PhD, is the Director of Performance Solutions at the Canadian Sport Institute Pacific in Victoria, Canada. His primary research focuses are in the field of nutrition and physiology interactions, as well as in environmental (heat and altitude) physiology. In this interview, we discuss the current best practices from and applied and scientific perspective in endurance and ultra-endurance sports.  

IN THIS EPISODE YOU'LL LEARN ABOUT:

-The importance of nutrition, and the simplicity of doing it well enough

-Periodised nutrition and the "train-low" paradigm (training with low muscle glycogen levels)

-Specific advice for ultra-endurance athletes (athletes doing events lasting longer than 4 hours) 

-Relative Energy Deficiency in Sport (RED-S)

-Trent's top nutrition advice as an applied practitioner to endurance athletes
