Gymbia’s Running CLinic

Gymbia’s running clinic supports the running community of Hackney Wick, Victoria park & surrounding areas.

We work with a wide range of people from those looking to run their first 10k pain free all the way up to ultramarathon runners looking to cross the finish line strong.

We specialise in biomechanical assessment & bespoke program design to create focused & efficient results in short spaces of time in running injury rehabilitation & performance.

The human body is perfectly evolved to run for long distances – we often find that desktop sitting creates postural issues that, combined with a faulty gait technique, can lead to pain & quick tiring while running.

 With the right coaching & instruction pain, slow run times & sluggish cardio can be a thing of the past!

We will help you reach your objectives through scientific strategies that reprogram your body in order to push performance to the highest level. Our programmes ensure your safety, reducing injury and allowing you to excel - just ask our clients!

I emailed Gymbia in the middle of the night after struggling to sleep with anxiety after picking up an injury while training for the London marathon. Sponsorship was pouring in and I was really worried I wouldn’t manage it. I met Jess and he immediately put me at ease. He has a track record of success and completed a really thorough assessment that worked out exactly where I needed to target my energies. He designed a great plan and helped me fit it around my life. We had clear goals and because he has run lots of marathons I knew I could ask him anything... from nutrition to chafing! In the last 4 miles of the marathon I knew exactly why he’d planned all the exercises we did together. I could feel the endurance training kicking in and it helped me to get over the line. I’m elated that I managed it. With only 6 weeks of training together I went from limping to finishing strong!

Client Testimonials;

"Jess, well…where shall I start. He is a true professional and really loves what he does. In less than 2 months to go until my first half marathon in Bath, he fixed my knee injury, after having it for more than 2 years. I was unable to run for more than 5 miles, as I had to stop during my training because of the pain and I was afraid to damage it further. I started to be very frustated. Then one day, my boyfriend suggested me to have a chat with Jess, as he was already a member of Gymbia. In less than 8 weeks, not only he fixed my knee issue, but he also gave a lot of motivation and suggestions to run more efficiently. We had an initial assessment where he analysed my posture and body flexibility and then he designed a customised program for me to do at home every morning. After less than 8 weeks and 10 sessions with Jess, I finished my first half marathon in Bath in 2h09 and I’ve registered to a second one in May in Hackney and a full marathon in September in Buenos Aires! I strongly recommend his running clinic to anyone who needs a treatment with an enthusiastic professional who loves his job and his patients."

Training with Jess has, with out wanting to sound cheesy, been life changing for my fitness, health, figure, work/life balance, career goals and mental attitude. His level of knowledge and continual self education in fitness, excercise, nutrition, psychology and all the rest the goes with it is extensive and forward thinking. But his strongest attribute is he genuine pleasure in seeing you achieve your goals and his passion for helping you do so. This year im training for the London Triathlon, completely changing my business and well on the way to having the body I’ve wanted for a long time and I put a lot of that down my time with Jess.

Our approach


We will go through a detailed assessment which will help us understand the factors that may be limiting your performance, any postural issues or injuries or any muscle imbalances that need addressing.

Our assessments are thorough, scientific and ensure that any training we do will target the root cause of injury, weak or underactive areas so that we can design a highly bespoke program for your individual situation


You will gain access to a dashboard that contains several health questionnaires. This will help us gain an insight into your lifestyle, wellbeing, diet and overall condition.


We will look at the steps we need to take to get you feeling your best for race day, the upcoming season, or that big game you’re prepping for.  Your coach will look at milestones as you progress, ensuring you are built to meet the demands of the marathon or the track.

We will structure your running periodisation correctly, so that you don’t burn out, which is a common occurrence among beginners & advanced alike who may be training for a big event.

Gymbia’s Running Clinic will get you to the start line in peak condition, so that you can reach your personal best or finish an event for the first time.

The Gymbia is not your average Personal Training Experience.
When I approached Jess about helping me train to run 180 miles in 7 days, I had my reservations. Previous personal Trainers I’d worked with tended to either give me generic routines that did not respond to my specific requirements, or feel that the only way to motivate is to be aggressive and loud.
From the outset, the Gymbia totally broke away form these stereotypes. Their bespoke and personalised approach was a breath of fresh air and made our training sessions something I looked forward to each week (most of the time!)
The programme was totally custom built for my needs. Jess delved into every part of the run, the distances I would be covering, the type of terrain it would be, right down to the clothing and equipment I would be carrying. Each week new elements would be added and adapted to ensure that all the muscles and sling systems were being worked in a way representative of the type of stresses they would be under. Jess also regularly would come to me with some new ideas or thoughts for me about the run. In that way the Gymbia became more like a support team than personal trainers.
Having done quite a bit of running previously, The Gymbia helped me become far stronger and more rounded than ever before. But what really made the experience special was there holistic approach to training.
A full body and skeletal assessment, analysing my frame and structure to tailor the programme to areas I needed it the most, was complimented by a detailed nutrition programme, thinking about my food in the months up to, during and after the run.
The programme was realistic and fitted within my wider routine, and that meant that the targets we set seemed achievable, and therefore that what they became.
It is important for me to understand how what I am doing works, and how it is benefitting me. Jess’s extraordinary understanding of the science of the body meant this was easy.
But perhaps most extraordinary part of the experience for me was Jess’s commitment to balancing Mind and Body. He regularly challenged me to move out of my mind into the body. To understand how I was feeling and to learn how to respond when I felt low. So when I was doing those long training runs and started to think that I might have to stop, I begun to learn how to move beyond those negative thoughts and tune into my body in order to keep going.
I couldn’t have been better prepared for my challenge. The Gymbia prepared me physically and mentally in a way that I had never been previously on other challenges. It made the whole experience so much more fun than I ever thought it would be. After 7 days I honestly felt that I could have done it all again!
Thankyou Gymbia – cant wait to work with you again!
