Jonathan Baker, Ph.D - High Performance Scientist

Jon’s a lifelong cyclist and has been involved in high-performance sport for almost 30-years.

First, as an elite-level MTB racer, where he realised what he didn’t know about training and performance – this is critically important. At the time, there wasn’t the technology, or access to scientific knowledge that we have now.

He now holds a first-class degree in Sport and Exercise Science and a doctorate in Exercise Physiology. It took ten years of study, then research, to fully understand the gaps in his knowledge that limited his racing career.

The Academic Approach

Jon's academic research investigated the interaction between the muscle bioenergetics and our integrated cardio-respiratory system. How this influences our fatigue mechanisms during exhaustive efforts and defines the “power-duration relationship” – essentially, our entire performance.

In the interim, he taught Exercise Physiology and Applied Sports Science topics, whilst also being a post-doctoral researcher investigating mathematical models to describe and predict exercise performance.

WorldTour Experience

Next, was four years working in professional cycling, first as a coach and then as a performance scientist managing projects from training, nutrition, altitude, equipment design and selection, data analytics, pacing and performance modelling etc.

Jon's professional athletes have won: the Elite British National Road and TT championship (double), the Tour of Yorkshire (GC). The Tour of Britain (GC) twice, stages of all three Grand Tours, and the yellow jersey at the Tour de France (for a few days). Plus, much, much more.

He’s also helped hundreds of amateur athletes and regular cyclists to improve their training and performance, whatever their goals. From young to old, from fat to fit, from road to dirt, Jon can fast-track you to a better place.

Performance Clinics

Jon has a weekly (Tuesday 8:30 -13:30) Performance Clinic at Cyclefit where he’ll help you solve your training and performance problems.

In a consultation, he will discuss (up to) three problems, questions, or topics of your choosing. You’ll leave with a deeper theoretical knowledge and practical strategies you can use right away.
Dr Jon Baker Consultation

A lactate profile test is a gold-standard way to determine your strengths and weaknesses and define your training zones. It provides a unique insight into your muscle physiology and context to your power data. We’ll also have time to discuss one problem, question, or topic.

What our clients say

  • "A very thorough, professional and personal service. I was keen to analyse my bike position after breaking my hip. The custom footbeds and alterations to my position feel really good, just wish I’d come sooner! Many thanks"


    Endurance MTB rider

  • "Hey Julian and Phil, I hope you are both well. I just completed a 21 hour week on my new 165mm cranks and I am in love. They feel so so great! Thank you for all your help. I’ve never felt so comfortable on my bike before. All the best, Hannah"

    Hannah Barnes

    National Champion / Professional Bike Rider

  • "I'm new to cycling so needed some support on finding a bike that would be right for me. Julian couldn't have been kinder or more supportive, he took time to find out what I wanted from my cycling and then looked closely at my physical structure to ensure that the bike is a comfortable fit for me. It really is a 5 star service and far exceeded my expectations."


    New Cyclist

  • "The personal service from both Phil and Julian is second to none. They have such a wealth of experience in fitting that they can almost tell at a glance if something is just a little off. It felt as though it didn't matter how long it took to get the best position possible - even for an amateur cyclist like myself. Can't recommend them enough."



  • "Julian was very knowledgeable and explained the fitting process very well. He came highly recommended and i completely agree. Very happy with the service. Instantly felt better on the bike. The pain i had in my knee went away right away. "
