Gray Caws Chi Running Instructor & Personal Trainer


I discovered a passion exercise and training in 2004 and was immediately fascinated by how the body works and how it can adapt and improve given certain stimuli. I became a regular runner and after a couple of years struggling with technique, I eventually discovered the Chi Running method after reading the book by Danny Dreyer. I found that my running efficiency greatly improved and that the niggles that were constantly holding me back where becoming less of an issue. In May 2010 I attended a workshop with Danny Dreyer, founder of Chi Running. This encouraged me to train to become one of only a handful of Certified Chi Running Instructors in the UK. 

In February 2012 I qualified as a Personal Trainer and in the August as a Chi Running and Chi Walking Instructor. During the Chi Running certification process I assisted Master instructors Marion Meesters in Amsterdam and Catherina McKiernan (winner of Berlin, London and Amsterdam marathons and Irish marathon record holder) in Dublin. I certified as a Chi Running Instructor in August 2012.

In 2013, realising the importance of exercise not only for fitness but for health and general well-being, I decided to study for a Level 3 Diploma in Exercise Referral and a Level 4 Certificate in Specialist Exericse (Exercise for the Management of Lower Back Pain). In October I returned to Berlin to assist Marion Meesters in training and assessing Chi Running Instructor Candidates from all over Europe.

I currently train clients on a 1-2-1 basis for running and also general health and fitness programmes. I also hold regular Chi Running workshops in London, across the UK and Europe.

For my continued professional development I see a Personal Trainer weekly and keep updated on current health, fitness and training developments. My current training is for the Royal Parks Ultra Marathon in October, and includes regular resistance strength and power, core stability, posture and flexibility. I focus on kettlebell and ViPR training as both are great whole body workouts and compliment my approach to running training. I also train barefoot and in minimalist shoes for both my running and resistance work. I believe this promotes better posture, proprioception and balance, helping develop stronger core muscles and natural movement. 

I have run several half marathons, numerous 10ks, the 2010 Virgin London Marathon and last year's Abingdon Marathon.
