Longevity

True longevity isn't guesswork, and it isn't a generic wellness trend. It's measured. Using the same clinical-grade diagnostics trusted by elite sports science — breath-by-breath metabolic mapping, research-grade biomechanical sensors, bone density and body composition scanning, and a targeted blood biomarker panel — we build a precise, data-validated picture of how your body is actually ageing, recovering, and performing beneath the surface. Sleep architecture, nutrition, and cellular health are assessed together, not in isolation, because they don't operate in isolation either.

Every session is private, single-client, and typically completed within a single lab visit. You leave with a personalised dossier — not raw numbers, but a clear, clinical strategy for the decades ahead.

Measure. Understand. Evolve.

"The sports science assessment was extremely informative and the written report particularly beneficial."

Lucy Sangar, Runner

"

“Now nearly 50, I had been trying to break the 3-hour marathon barrier for over 10 years and visited Performance Evolution to see if they could get that extra 5% out of me. Having reviewed my diet, training plan, technique and general conditioning, they prepared a fitness programme that I could fit in around my work and running schedule. Come the day and I achieved my goal, completing in 2:58:52. Happy as!“

Adrian Cooper, Runner

"I got on the podium at the World's and you were a big part of that. I know you can continue to help me with your skills and the facilities you have, which I think are exceptional."

Simon Fawcett, GB Age Grouper

“Having had surgery on my leg, and wanting to get some strength back, I decided to take up road cycling. Performance Evolution helped me improve both my conditioning and my endurance. Over the years they have offered knowledgeable, up-to-date advice on my technique, the physical demands of various races and nutrition. I qualified for the age group world championships.“

Marty Clark, Cyclist

“I went to PE to get some advice on getting back into running and generally improving my fitness after a few years of cumulative weight gains had taken a bit of a toll. Their assessment was really detailed - they highlighted potential weak points in my body and helped me strengthen them, so that I could avoid injuries in the future. I return regularly for advice on my running and, now, also triathlon, with Barry helping me tackle open water swimming. I recommend PE wholeheartedly.“

Matt Rayner, multi-sport enthusiast

"It is clear that Barry loves the sports physiology and science and is very knowledgeable. I really enjoyed this session."

Richard Worth, Doctor

"Barry gives so much thought and time and effort - he's really encouraging and makes it fun. He knows how to manage people, and creates such a lovely environment. Everything is positive."

SallyAnn Soper, GB Age Grouper

"Thank you for your time on Sunday and for sending this over so quickly. It's really helpful.

I swam this morning and tried to think about some of the high elbow tips."

Lucie Marie Edwards, Novice Swimmer

"The science and testing capabilities add a different depth, and cover all abilities, it was engaging."

David Poland Coach and GB Age Grouper

"I learned so many different things about sports technique but also about myself. If I can retain what I've learned, that will put me in a much better position both mentally but also physically... I've got a lot out of it."

Recovery & Resilience — Understanding your body's recovery patterns and building the mental resilience to perform under pressure, whether that pressure is a race, a event, or simply daily life.

Preparation & Strategy — Translating insight into a clear plan for the specific demands ahead, so you arrive prepared rather than hoping for the best.
