What our participants say

[I really liked] combining the practical with the theory. The walk on day 3 was excellent, and then combining that with the indoor walking and the practice was a good finish to the course. I thought Gray was very knowledgeable and welcoming, very relaxed and made everyone feel comfortable. (November 2023)

Sammi - Company Director


Company Director, Fiit

Gray is a great and passionate teacher with different fields of expertise. He has a broad vision on breathwork and on its practical uses. [I particularly enjoyed] the group connection and the playfulness.

Gray is a firm believer that optimal mental and physical health can be achieved through efficient breathing, a focused mind, and body awareness. As a specialist personal trainer, running coach, and breath coach from the UK, Gray is a master in the Oxygen Advantage® and Buteyko methods.

With training from globally-renowned coaches like Patrick McKeown (breath), Lee Holden (meditation, tai chi, and qigong), and Danny Dreyer (ChiRunning), Gray has honed his craft and is an expert in his field.

He has had the privilege of guiding breathwork sessions on the ASICS Movement For Mind programme, working closely with prominent mental health researcher, Dr. Brendon Stubbs. Launched in 2021, this programme documented the mental well-being of almost 200 volunteers, with remarkable results. In fact, 70% of participants became more active after completing the program, a testament to Gray’s expertise and guidance.

Elaine Jackson Running Coach

Elaine Jackson

Elaine is thrilled to be coaching on the Costa Brava alongside Gray.

With a background in dance teaching, Elaine initially took up running to enhance her fitness but quickly discovered it offered much more. Running brought her a sense of freedom and space, a refreshing escape after a day at school.

Over the years, Elaine has participated in various events, ranging from 5k races to the London Marathon in 2016. She became a qualified running coach in 2017, driven by her passion for helping others progress, achieve their goals, and most importantly, enjoy the journey.

Elaine’s journey with Gray began in 2018 when she joined as a client on the Costa Brava. The experience left such a lasting impression that she continues to share it with everyone she meets. In 2021, she was overjoyed when Gray invited her to join the adventure as a coach, creating unforgettable memories with the scenery, people, camaraderie, and fun.

Now, as an Oxygen Advantage coach, Elaine is looking forward to experiencing this magical adventure once again and hopes you’ll join her.
