Great first meeting and assessment with Claire. A huge amount to take in but Claire guided me through the first stage. Have some clear first steps to work on in my journey to improving my hydration and nutrition to support improved training and race performances.

“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. My performance rocketed and I completed my two dreams in one season. Medalling at the European Middle Distance AG triathlon and smashing my first ironman”

Since working with Claire, she’s made a huge difference to the way that I’ve been able to execute my training sessions, bring the energy that I need at the right times to competition, and get the most out of recovery. I wholly recommend giving Claire a call. The biggest thing to take away is that everything that we do is absolutely manageable!

“Your encouragement means a lot at a time when work and training is difficult and I cannot see the journey back to ‘normal’….. your positivity is highly contagious – I feel better already “

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.

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.

Thank you for your help over the last few months. It was very helpful and I learnt many things I was not aware of before.

~ Giulia Runner
star testimonialstar testimonialstar testimonialstar testimonialstar testimonial

training for my first Ironman I knew how important getting my nutrition right would be leading up to the race and on race day. Claire has helped me more than I could have imagined. Lifestyle changes we have discussed and implemented have meant that unlike any fad diets before; I am leaner and letting my food be the proper energy and recovery source it should be. Claire is always supportive, really cares about the people she works with and I love her approach to nutrition; working with what you have to make the best out of your body.

I’ve learned so much stuff I didn’t even know existed, different types of proteins, when to take, when to take dairy, how to stay full, what’s a good probiotic to boost my immune system…I’m always learning, I think I’ve really improved” . –

“ Claire went into a lot of detail, preparing nutrition plans for me and for ½ and full races and also assisted me with recovery nutrition. She is very supportive and knowledgeable. I would highly recommend her”

Claire challenged my unhealthy food beliefs in an empathic manner and suggested changes that were specific and achievable whilst continuing in my recovery from anorexia. “her knowledge and support have been really valuable in the progress I have made over the past few months and I would definitely seek her advice in the future.

~ S Business Professional

I started working with Claire when I realised that I thought I knew what I was doing but I really didn’t when it came to sports nutrition. I’d been competing at an age group level internationally in triathlon and since working together, my performances have improved together with making podium places as well as making the jump up to 70.3 a successful one.

~ Jess Doctor and World-class Ironman athlete

“exceptionally supportive …excellent knowledge of nutrition both in terms of supporting sports performance but also in optimising health. Claire’s background in long distance triathlon herself means that she is able to support in ways others wouldn’t …..her race and training experiences. I (would) recommend Claire for anyone who is looking for support with their nutrition – either for optimising everyday health and wellness or for enhancing and supporting sports performance”

~ Julia Business professional and Ironman triathlete

I felt at the time when I started with Claire that the quality of my life wasn’t very high and I was really struggling to enjoy my training. I certainly wasn’t enjoying food and it’s safe to say that she worked with me every step of the way to transform my life everyday.

~ Laura Business Tech Marketing Professional and Athlete

“ frankly i hadn’t got any knowledge….Claire was amazing! She helped me plan out my nutrition… to make sure i was getting the best performance (this) allowed me to fully concentrate on the competition.. “best competitive season of my life so far, gaining my first GB senior vest competing at the Athletics World Cup, 2nd place at the British Championships and becoming England Champion gaining my first England Senior International vest”

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 really enjoyed the discussions with Claire. She gave me really good and relevant advice which helped me a lot to overcome my problem.

I was a relatively competitive athlete but wasn’t getting any better. My relationship with food was challenged, but Claire Fudge unzipped all of my psychological hang-ups and addressed it with science. It freed me from worrying, and I actually started enjoying food again. It’s an educational investment, a change-in-whole approach, and something I will carry through for life. I can’t recommend her highly enough.

~ Richard CFO and Ironman Age Group 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.

“I thought I needed a diet plan; but that is exactly what I didn’t need. I gained the knowledge and support and the balancing of everyday life around training along with personal life too”.

The work we have done together has covered race day nutrition, everyday nutrition, and has helped me have a better relationship with food. So often we have coaches for the sports we do, yet no guidance or coaching when it comes to nutrition. Working with Claire has really helped up my performance. Thanks to Claire and Fourth Discipline for all the continued support.

“revolutionised how I eat during …. big sessions. From my former race snacks mindset to a proper fuelling strategy-it’s made a demonstrable difference in my form”

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.

I went to Claire looking for a quick fix, however Claire explained in detail the process and why I needed to take a different approach to hit my goals. Claire was very encouraging, providing weekly support and further analysis on my progress.

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!”

~ Sarah Director and Adventure Endurance Cyclist

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.

A big thank you for helping me to manage my eathing regime. Meal advice before the race seemed to really help keep my stomach settled on race day. I was very pleased with my race results. Really impressed by how good I feel and not so tired. A lot of this has to do with my new meal plans for training and racing.

Frequently Asked Questions

Limited monthly availability
Which service is right for me?

The right service depends on whether you are looking for support as a driven professional, a professional who competes, an athlete, a team, a research organisation or an event organiser.
If you are unsure where to begin, book a discovery call and we will guide you towards the most appropriate pathway.

Do you only work with professional and elite athletes?

No. I work with professional and Olympic-level athletes, athletes on talent and high-performance pathways, competitive age-group athletes and professionals who train, race or compete alongside demanding careers.

The level at which you compete is less important than your commitment to improving your health, fuelling and performance.

I also support driven professionals who are not athletes but want to improve their energy, focus, resilience and long-term health.

What is Personal Performance Precision?

Personal Performance Precision is my approach to creating nutrition support that is fit for purpose and designed around the individual.

Generic plans are built for an average person. They do not account for your physiology, health history, symptoms, training, workload, lifestyle, preferences or goals.

Personal Performance Precision brings these factors together with clinical expertise, performance science and meaningful personal data. This allows us to identify what is affecting your health and performance, then engineer a practical strategy around your specific needs.

Like a tailored suit rather than something taken straight from the rack, the strategy is shaped around you: how you live, how you move, what your body needs and what you are working towards.

The result is not simply more nutrition information. It is a clear, personalised approach designed to support your energy, health, recovery and performance now and over the longer term.

What is the difference between a dietitian, a nutritionist and a nutritional therapist?

In the UK, dietitian is a legally protected title. Dietitians are regulated healthcare professionals qualified to assess and treat nutritional problems, including those associated with medical conditions.

The titles nutritionist and nutritional therapist are not legally protected, so qualifications, training and experience can vary. Registered Nutritionists and nutritional therapists who belong to recognised professional bodies may have completed relevant training, but their scope of practice differs from that of a registered dietitian.

As a Registered Clinical Dietitian and High-Performance Nutritionist, I combine clinical assessment and evidence-based care with specialist sports and performance nutrition.

This is particularly important where symptoms, blood markers, low energy availability, gut issues, injury, REDs, disordered eating or a medical condition may be affecting health and performance.

Do you work with people with eating disorders or REDs?

Yes. I provide specialist clinical and performance nutrition support for athletes and active individuals with eating disorders, disordered eating, Relative Energy Deficiency in Sport (REDs) and low energy availability.

Support may include nutritional rehabilitation, restoring adequate fuelling, reducing nutrition-related risk, supporting training and recovery, and working alongside doctors, psychologists, physiotherapists, coaches and other members of the multidisciplinary team where appropriate.

Where clinical risk is present, the priority is always safe, coordinated and appropriate care.

Do you write meal plans or diet plans?

A clear plan for what, when and how you eat can be valuable, but lasting change requires more than a prescriptive meal plan.

Where appropriate, I provide personalised meal structures, fuelling plans, practical food ideas, competition strategies and guidance around timing, recovery and preparation.

These sit within a wider approach that considers your health, schedule, training, travel, preferences, symptoms and goals.

The aim is to give you a strategy you can understand, adapt and sustain rather than a rigid plan that only works temporarily.

Do you offer one-off consultations?

Most individual support is delivered through a structured programme rather than a single appointment.

A first consultation begins the process of understanding your symptoms, patterns, data, health history, training demands and goals. Follow-up support allows recommendations to be implemented, reviewed and refined.

One-off specialist consultations may be available for clearly defined needs, such as an expert review or sweat sodium testing.

Please contact the team to discuss the most appropriate option.

What happens after I enquire?

You will be guided towards the service that best matches your goals, health needs and performance demands.

Where appropriate, the first step will be a discovery call or initial conversation to understand the support you are looking for and whether the service is the right fit.

You will then receive clear information about the recommended pathway, what is included, the expected timescale and the investment required.

A limited number of new clients are accepted each month to maintain the depth and quality of personalised support.
