In this webinar we discuss the science of ultra-running. We take an evidence based approach to nutrition in this sport that is growing rapidly. However, the science is limited in places and we turn to the practical considerations and applications by filling in the gaps. How do we translate the findings of various studies into a successful plan for race day? What are some of the considerations that are highly specific to ultra-running? When do we start to prepare? What are the best products and how are self supporting races different?

Drs Nick Tiller and Emily Russell join us in this webinar to share their opinion as a scientists and practitioner but certainly also as experience ultra-runners. Dr Asker Jeukendrup discusses some of the science and some of the gaps in our science.

Q&A session

Rewatch the Q&A session with the speakers.


Ultra-running is a sport that is growing rapidly. There are more events, and more athletes are participating in ultra-running. Ultra-running is also a sport that requires appropriate fuelling and hydration strategies for performance, but also for event completion without any detrimental effects. But what is the evidence for different sports nutrition strategies during ultra-running? Are there specific carbohydrate and hydration recommendations? And what about electrolytes? Watch this webinar for an evidence-based overview of nutrition strategies for ultra-running. Discussing the science, and outlining where more research is needed.
