Struggling with Nutrition & Performance?

Feel like you’re left spinning your wheels despite training hard? Maybe you feel overwhelmed by conflicting advice, social media pseudoscience, the latest trends and supplements, you have tried them all, but you are more confused with a lack of real results ?

Potentially your performance has plateaued. You’re training hard but still battling fatigue, injuries, poor recovery, and stagnant body composition. Leaving not knowing what to change or how to implement those changes ?

Perhaps you have gut issues holding you back. No matter what you do, your GI issues (distress/ runner’s trots) during training or racing is sabotaging your performance, and pushing you from the podium ?

Possibly your struggling to manage your energy. Leading to often burning the candle at both ends with little room for prioritising nutrition, sleep, and recovery, leaving you exhausted and reaching for less appropriate foods just to pick you up. You are not reaching your full potential for training.

Poor nutrition and hydration are among the top reasons for a DNF (Did Not Finish). Don’t let it be yours.

Achieve Peak Energy, Recovery & Stamina

Imagine waking up refreshed, recharged and recovered. You have refuelled well and you can tackle tasks at work with ease. You know what to eat and you feel alert in the afternoon, you have a sharp focus and are ready to train again when your finishes. You have energy.

You can think on your feet about what to eat when. GI symptoms have disappeared and you are fully supporting your body to prevent injury.

Picture a time before that big A race. You are at the start line. You are confident, focused race-ready, knowing you’ve nailed your body composition and fueling plan.

Envisage, collecting your medal. Standing on the podium.Smashing your personal best because you have a personalized nutrition strategy that works with your training plan, with your body, for your unique physiology.

Sam

No one loves looking at historical stats more than a triathlete, and I can see through all my data my weight has dropped marginally compared to this time in previous years, my body fat is down some 6% and most importantly my power hasn’t dropped. I run better, I feel better, I’m not getting injured, and I sleep well.

Stef

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.

Andrew

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.

Sophie

Frankly, I hadn't had any knowledge... Claire was amazing! She helped me plan out my nutrition to ensure I was getting the best performance. This allowed me to fully concentrate on the competition. It was the best competitive season of my life so far—gaining my first GB senior vest, competing at the Athletics World Cup, securing 2nd place at the British Championships, and becoming England Champion, earning my first England Senior International vest.

Seanin

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

Sarah

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!

Ella

I could start to eat intuitively again; I recovered my menstrual cycle and eat intuitively without any fear; Claire was there with support and guidance.

Jen

Instrumental in uncovering my coeliac disease, supporting me to make the necessary changes to a gluten-free lifestyle, which alleviated by IBS symptoms. This in turn positively impacted my fertility. Can’t thank Claire enough for her tailored expertise which also extended to advice around diabetes management during pregnancy!

Richard

Help with a long standing issue, It was her personality, honesty and openness which gave comfort in trying her methods. Over the year that I have spent working with her, I have gained the knowledge and insight to manage my symptoms, giving me a new found sense of freedom. I would wholeheartedly recommend Claire to anyone who needs nutritional advice.

Charmaine

Helped me relearn that “Food is food”. Fed up of seeing zero results through yo-yo dieting, I had tried intermittent fasting, Keto and various other diets. I wanted a lifestyle change and wanted to be able to enjoy food without the guilt associated with "bad food". I can now enjoy eating fruit without feeling guilty! I'm confident I will reach my goal weight comfortably and remain constant.
