The Practice of Endurance Nutrition
If you have struggled to find sound, evidence-based nutrition advice or fuelling strategies that are well adapted to your endurance or adventure goals, you’re not alone.
We can help you achieve the results you simply haven’t been able to reach on your own. Applying mainstream diet plans and nutrition strategies to endurance and mountain sports is notoriously challenging – and when your fuelling options are further limited by extreme environments or remote settings, the challenge can feel even greater. Since 2011, we have built our reputation as the endurance and mountain sports nutrition specialists. From our base in Chamonix, Europe’s adventure sports capital, we support mountain sport enthusiasts, endurance athletes, adventurers, coaches, sporting associations and brands around the world to get the most from their sport, by providing nutrition strategies to survive and thrive in extreme situations and demanding environments.
High Performance

Whether your sights are set on an Olympic medal, a mountain summit or the finish line of a race, we’re here to help you get there.
With the emphasis firmly on you and your goals, we help you identify the nutrition changes you can make that will provide the biggest benefit to your performance. We debunk the myths that surround sports nutrition and replace misconception with sound, easy to implement nutrition strategies personalised to you.

Rebecca is a true professional –she is friendly, approachable and flexible.I started working with High Performance Dietitian in 2019 in an attempt to better gain an understanding of the nutritional needs to support my athletic goals particularly in the context of mountainous ultra-running. I was at all times impressed with her ‘food-first’ approach and the application of fundamental scientific principles –there were no fads or ‘marginal gains’. Rebecca enabled me to develop a long-term nutritional strategy to support multiple and varied performance goals (both training and racing) rather than focusing on short-term goals. I certainly saw my overall performance improve over the period I worked with Rebecca.Josh Baker-Dyos - Ultra Runner

I wanted to understand more about nutrition so that I could train harder.I was extremely impressed with Rebecca: she spent time understanding my goals and what I wanted to get out of the consultation, and then provided intelligent advice tailored to my needs. She is passionate about her subject and what really stood out was how much she cared about my performance. Rebecca provided me with a detailed nutritional plan to support my training needs and also gave me excellent guidance and support implementing this plan. Rebecca is both personable and professional –a real pleasure to work with. I would highly recommend her to any athlete who wishes to learn more about nutrition to enhance their performance in sport.Katie Thompson - GB age group triathlete

When you have Rebecca with you, it is literally like she is by your side, pushing and willing you on!
