See Claire in Action

Claire’s presentations combine science, storytelling and real-life experience to make complex subjects understandable, relevant and actionable.

From the demands of elite sport to the realities of busy professional life, Claire connects evidence with the decisions people make every day.

Is Your Audience Receiving More Information but Less Clarity?

The pressure to perform has never been greater.

Yet professionals, leaders and athletes are surrounded by conflicting nutrition advice, health trends, new technologies, supplements, quick fixes and generic plans.
Knowing more does not always lead to better decisions.

People may understand that nutrition, sleep, hydration and recovery matter, while still struggling to apply that knowledge around demanding workloads, travel, family responsibilities, training and competition.

The result is often inconsistent energy, reduced concentration, slower recovery and growing uncertainty about what evidence to trust.

Claire closes the gap between information and action.

She gives audiences a clearer way to understand what influences their health and performance and how to make meaningful changes that work beyond the event itself.

Unleash the Inner Athlete

Applying Elite Performance Principles to Work and Life. This established presentation can remain available for organisations that respond to the idea of bringing an athlete’s approach to preparation, energy and resilience into professional life. It should sit as an additional tailored presentation rather than the main positioning for the entire page.

Topics can include:

Fuelling high-stakes decisions
Building resilience under pressure
Managing energy across demanding schedules
Separating evidence from performance trends
Sustaining health while pursuing ambitious goals

Meet Claire Fudge

Clinical Dietitian. High-Performance Sports Nutritionist. Nutritional Engineer. Endurance Athlete.

As Clinical Director of 4th Discipline, I bring together more than 23 years of clinical nutrition, elite sport and high-performance fuelling experience.

I work with professional and Olympic-level athletes, elite performance pathways and world-class programmes, collaborating with medical, coaching and sports-science teams to ensure athletes receive the highest level of joined-up care.

As a Registered Clinical Dietitian and High-Performance Sports Nutritionist, I look beyond food alone. I consider the full performance picture: physiology, medical history, training load, recovery, gut health, body composition, energy availability and long-term health.

I also understand the demands personally. As an endurance athlete and business owner, I know what it takes to work hard, train hard and continue performing when time, energy and recovery are under pressure.

That describe myself as a Nutritional Engineer! 



I identify what may be limiting performance, connect the clinical and sporting data, and build a personalised fuelling strategy designed around the athlete, not just giving a generic plan.
The aim is not simply to produce a result at the next competition. It is to build robust, resilient athletes who can perform at a high level now while protecting their health and sporting longevity.

In Claire, I have found a dietitian who not only is a specialist in nutrition, but also really understands the specific demands of an athlete. She acknowledges that one size does not fit all and really considers all the different aspects in optimizing nutrition for me as an individual. Most importantly, she helps me understand every little step of the process so that I know how to fuel myself even when she’s not around.

The moment someone says to you, ‘you know the symptoms you are experiencing are not normal’. Was really the moment the journey began to experiencing a normal existence. “years with food intolerances, …. impossible to control …..I am now free to live my life without symptoms and all of the related issues I was experiencing (anxiety about going places, worrying if I was going to be ill when I went out, the list continues…) . all of the guesswork (was removed) ….introducing each element in bitesize chunks ensured it wasn’t in anyway daunting, and allowed the outcome to be obvious . Having the support and expertise throughout was such a huge benefit, and now I can everyday apply the principles learnt with confidence, knowing they are specific to my needs. Being normal feels amazing!”

A friend who is a no nonsense athlete was working with Claire and I thought she would be good for me as although not a ‘real’ athlete myself, I wanted to understand how to fuel for 70.3 training and simultaneously sort out my ongoing chaotic relationship with food and eating for ‘normal life’. I knew Claire had an understanding of and worked in both areas.

I’ve been running for quite a few years, but I just kept running out of energy. Training for a marathon, I got in touch with Claire. I thought she would just give me a food plan, but she basically educated me on what I needed to eat and the right food groups to eat together. It was just an absolute game changer. I did my marathon with absolutely no problems—didn’t once run out of energy.

~ Joanne Managing Director and Athlete

I had a sweat test done by Claire – I’ve yet to put the results into practice, but really enjoyed our discussion. She explained the process and how to put the results into practice very clearly. She also seemed to me to have a very balanced view (it was not just a sales pitch for Precision Hydration!) which gave me a lot of confidence in her advice.

“Claire’s methods didn’t leave me feeling hungry or depleted of energy like fad diets can, in fact I couldn’t quite understand how I was able to eat quite so much and feel so full and strong………what a difference having a nutrition plan to work with made.

Where I’ve really benefited from working with Claire Fudge is around the timing of food around my training, but also particularly around travel. Working with Claire on a plan so that I don’t go for chocolate in the airport or at the petrol station, but have snacks and planned timing along the way has really been beneficial. She’s great at delivering helpful tips that are quick and easy to do.

I first met Claire Fudge of 4th Discipline in the summer of 2021 for sweat rate test to better understand his electrolyte and hydration requirements for training for a Guinness World Record attempt for an endurance event.
I came away thinking I would like to work with the 4thdiscipline team as they provide nutrition coaching for performance to professional athletes and people like me who have been blundering through the nutritional needs of heavy training.
4thdiscipline know their stuff and their engagement with me was focussed on my individual needs basing my education and planning on science. At all times they worked with me in a calm, supportive and realistic fashion.
For anyone looking to improve their understanding and knowledge of food and sport I can highly recommend them!

Struggling with allergies, intolerenaces and anxiety around food for many years had a huge umpact in my daily life, being able to properly fuel for marathon training, recovery and race days. Symptoms have improved dramatically, my training is much more efficient and my confiedence around food has grown. I have lost count of the different diets and plans that I have tried; I have seen a really positive change. I really couldn’t recommend Claire any more highly.
