Meet the Coaches behind NxP
I'm Lily, a registered performance nutritionist. With a background that includes tackling both ultra-running and triathlon myself, I've seen firsthand how the right nutrition can transform your energy, recovery, and race-day performance.
My approach is evidence-based, but it's also grounded in real life. I understand that we aren’t all full-time professional athletes, and are often balancing training with a job, family, and other responsibilities.
You should feel empowered by your training, not exhausted by it.
My goal is to help you achieve your athletic goals in a way that’s sustainable and helps you enjoy every part of the experience.a
I’m Dr. Kelsie — performance nutritionist, hybrid coach, and founder of NxP Coaching.I blend science with strategy, combining evidence-based nutrition with real-life coaching that works. Not just on paper — but in your actual life.
I know what it’s like to juggle intense training with a full calendar and still wonder if you’re fuelling right, recovering enough, or training the right way at all.
That’s exactly why we have created these nutrition programmes: A high-touch, high-impact coaching experience for athletes that want to fuel better, manage body composition and perform at their best.
Nutrition does not have to be complicated — you need a system that fits!dar and still wonder if you’re fuelling right, recovering enough, or training the right way at all.

Hydration: Individualised hydration protocols to prevent dehydration and optimise performance.
Distance-Specific Nutrition: Tailoring your plan to the unique demands of sprint, Olympic, half-Ironman, and full-Ironman distances.

We also offer support with body composition and weight management!
I had an amazing experience working with Lily as my sports nutritionist. When I signed up for a full Ironman, I knew that if I really wanted to hit my goal, I had to get my nutrition right. From our very first call, she took the time to get to know not just my training and goals, but also my lifestyle and preferences — and she made sure we were a good fit to work together. What I really appreciated was how practical and evidence-based her approach is. She always explained the reasoning behind what we were doing, often backing it up with research, which made it so much easier to trust the process and stick with it. Her plans never felt generic — everything was tailored to me and my race. She listened, adapted when needed, and the results showed. Within just a few weeks, I noticed big improvements in my energy during and after training, plus my recovery was way better. On top of her knowledge, Lily is super supportive and genuinely celebrates your wins with you. She explains things clearly, in a way that actually makes sense, and that kept me motivated the whole way through. Thanks to her guidance, I not only finished my first Ironman, but did it in under 10 hours. Most importantly, I nailed my fueling strategy on race day — hit the numbers we practiced and had zero stomach issues. I honestly couldn’t recommend Lily enough to any athlete who wants to take their performance to the next level.
I worked with Lily in the build-up to my 70.3 and even though it was only for a few months, her support made a real difference. She helped me fine-tune my nutrition plan so I knew exactly how to fuel before, during, and after training sessions, and I went into race day feeling confident rather than guessing. Beyond the immediate race prep, she also gave me clear guidance on how to approach future races and what to focus on in the days leading up to competition. Her advice was practical, easy to follow, and tailored to my goals. I feel much better equipped for racing now.
I’ve been working with Lily for the last six months to get ready for my Ironman in October and honestly reaching out to her was the best decision I could have made. I don’t think I would have come this far feeling this good without her. The knowledge she has is incredible and she’s always there to answer my questions, give me support and tweak anything I need. On top of that, Lily’s easygoing and welcoming personality makes the whole process so much easier it really feels like I’ve got someone in my corner who cares. Thanks to her help, my training has come on so much and I feel confident heading into October knowing we’ve locked in everything we need.

Hyrox Performance nutrition
For the hybrid athlete, our coaching addresses the unique blend of strength, explosiveness, and endurance required for Hyrox. We'll help you with:
Race-Day Fuelling: Strategies to maintain energy and power through each station.

Food Quality & Recovery: Focusing on the right composition of foods to support muscle repair, growth, energy levels and overall health.

❝ I'm loving all my training and guidance form Kelsie so far! I started with Kelsie after winning her survey give away (NxP), after a month of coaching I decided to continue working with her as she’d been so good. Before I was struggling to balance running, strength training, conditioning and was feeling burnt out trying to fit everything into my programming and make sure to eat/sleep enough - Just all round trying to do too much. Having Kelsie’s guidance has put all of that stress aside, she’s brilliant, caters for your time frames, goals and gives nutrition guidance to help fuel your training and recovery. I’ve found the running programming has been fantastic and I’ve learnt so much already. Have loved the structure of training and the focus on the importance on recovery and nutrition too. Kelsie is very knowledgeable and just brilliant all round, I’m loving it all so far and looking forward to the next few months! Thank you so much so far ❞
RUNNING PERFORMANCE NUTRITION
Tackling single-day and multi-day events requires a specific nutritional approach. Our program for endurance athletes will cover:
Race-Day Fuelling: Creating a fuelling strategy for extended durations, including managing GI issues and "gut training" to prevent stomach problems.
Hydration Strategies: Building and adapting your hydration plan based on climate and personal sweat rate, + sweat sodium concentration.
Lightweight Fuelling: Developing low-weight, high-density fuelling strategies for easy carrying.
Mapping Your Fuel: Strategically planning your nutrition based on the race route, whether you're relying on aid stations, a support crew, or a self-supported approach.
Preventing Decision Fatigue: Making all the critical fuelling decisions and backup plans well in advance, so you don't have to think about them during the event when your energy is low and decision fatigue kicks in.
The Psychological Impact of Nutrition: Understanding how proper fuelling affects your cognitive function and motivation.
Been working with Lily since the start of the year. Lily is always ready to listen and help. Helped me make small changes throughout for day to day but also been a massive help as I prepare for my first Ironman. All the tips, recipes & knowledge she has shared has been massive for me. Very grateful for all of her support.
Big thanks to Lily for getting me to the start line in one piece and to the finish line in 56:46 at the CRUK London Winter Run 10K. The plan you put together for me kept me motivated, injury free and on target for the finish time I was hoping for. Great nutrition advice. Look her up if you’re looking for help in reaching your goals!

FREQUENTLY ASKED QUESTIONS (FAQs)
What exactly is included in the nutrition programme?
You’ll get a fully customised nutrition plan tailored to your sport and goals, expert-led coaching, and regular check-ins to keep you on track. We’ll provide macro targets, fuelling and recovery strategies, and clear guidance on how to eat around training and race day. You’ll also get performance data reviews to make sure your nutrition is supporting your progress week by week.
Is this just a training plan?
Nope! This is coaching, not a one-size-fits-all meal plan. You’ll get expert feedback, accountability, and strategies that adapt as your training and goals evolve. It’s personalised nutrition support, not a static PDF.
Do I have to track my calories?
Nope — not if you don’t want to. Some clients love tracking because it gives them data and structure. Others prefer a more intuitive approach using habits, portion guides, or meal templates. We’ll find a method that works for you, your goals, and your lifestyle. This isn’t about perfection — it’s about progress and long-term results.
Do I need to be training for a Hybrid event to join?
Not at all! While we specialise in fuelling strategies for triathlon, HYROX, and endurance events, we also work with the general population on health, energy, and weight management. Whether you’re chasing a finish line or simply want to feel, perform, and recover better in everyday life, this programme adapts to you.
How much access do I get to you?
You’ll have regular check-ins, access to your coach through your coaching app, and responses within 24–48 hours. Depending on your plan, there may also be video reviews, dietary analysis, and ongoing WhatsApp or email support. We also have a community WhatsApp group where people ask common questions.
What if I go on holiday / get sick / life gets busy or my training changes?
Life happens — your plan is built to flex with you. We adapt your nutrition week to week so you stay on track without guilt or overwhelm. This isn’t an all-or-nothing approach. Your training changes? Don't worry we will adapt the nutrition to match!
What if I have preferences or dietary restrictions?
No problem! Whether you’re vegan, vegetarian, pescatarian, or have allergies/intolerances, your plan will be built around your needs without limiting your performance.
Can this help with weight management as well as performance?
Yes — many of our clients want to balance health, weight goals, and performance. We’ll help you fuel properly for training while still supporting your body composition targets.
Ready to take your performance to the next level?
Apply now to join the next round of the programme and finally feel unstoppable — in your races and in your life.
