about John Stocker


I love empowering individuals to achieve their pinnacle of health. I incorporate my knowledge and passion with precision in every training session.

I transformed my life through fitness and am dedicated to helping others do the same.

My journey started as an unfit skinny teenager wanting to gain size, soon realising that this wasn’t going to happen but in turn finding my love for running and endurance sport. I wanted to push myself to find where my limits were, I’m still searching.

I’m a fitness professional and have worked within the fitness industry for over 25yrs, I’m a qualified Personal Trainer and Sports therapist and have worked with a wide range of athletes.

What my clients say about me

I’m proud to have worked with a great many clients from running their first 5km to completing ultra marathons. I’ve helped people rehab from long term injury, supported recovery after illness and supported them to improve their confidence and fitness. Find out what they have to say

I started training with John in 2009, when I wanted to run my first marathon, and have not looked back. John has played a pivotal role in my fitness journey, offering invaluable mental support during my cancer treatment and aiding in my recovery from a hip replacement, the swiftness of which pleased the surgeon. 

John ensures that every training session is productive, enjoyable and engaging. As a result of John’s knowledge and passion, I consider my fitness level as very good for someone approaching the age of 60. I also highly recommend his sports massages, which have contributed significantly to my overall well-being.

I have trained with John now for nearly ten years, he took me past my primary goal of running a half marathon and onto ultra marathon running of up 100 miles, this would not have happened without John’s encouragement.

His knowledge and enthusiasm for training is truly contagious and inspiring. No matter what your goals are, whether its to run your first 5K or the longest of ultras John will guide you through it. If you are looking for a personal trainer you will find no one better than John Stocker.

I first started seeing John for sports injury rehab in 2021 on the recommendation of a local Bicester physiotherapist. After getting me back to running, I started training with John to keep myself injury free and to help me reach my fitness goals.

John has since helped train me from knocking 45 minutes off of my marathon PB to completing my first 100 mile race in 2024 whilst remaining injury free. John is an excellent PT and coach for anyone looking to start or build on their fitness journey

Don’t be fooled into thinking John is just for the super runners of the world! I really do not enjoy exercising normally and, before John, had tried to motivate myself with several different personal trainers and gave up every time.

In 2017, very overweight and not able to run even half a mile, I started training with John. He was just incredible. He works with you, wherever you’re at physically and mentally, and makes you laugh while you’re doing it!

I’ve lost 4 stone training with John, he’s trained me all through my first pregnancy, and now holds my 6-month-old while I get back in shape post birth! Starting training with him was the best decision I’ve ever made for myself, physically and mentally. I can’t recommend him highly enough for anyone looking to improve their fitness and wellbeing.
