meet the oneathlete team

The oneathlete team comes with years of combined experience in professional and elite sport and have achieved success at the highest levels. On top of this, we’re enthusiastic and love what we do. Together we are oneteam and we have a strong common belief in what oneathlete represents and we’re excited about supporting athletes to become the best they can be.

Firstly, I’m a coach. I love coaching. I love working with athletes and I love it even more when I help them to be successful. I started working as a Strength and Conditioning Coach in 2008 and since then I have spent 100′s…make that 1000′s of hours in the trenches training athletes to develop the physical characteristics which will make them better than their opposition.

I have worked with athletes from 28 different sports, from grassroots level through to elite sport, including Paralympic and World Champions. I’m a UKSCA Accredited Strength and Conditioning Coach with advanced certifications from the National Academy of Sports Medicine (NASM) for Performance Enhancement and as a Corrective Exercise Specialist. I’m also a course tutor for the NASM and I’m currently studying for my Masters of Research in Exercise Physiology with a specific focus on athletes with cerebral palsy. In 2013 I won the Nottinghamshire Performance Coach of the Year award and was recently appointed as the TeamGB Strength and Conditioning Coach for the Rio 2016 Paralympic Games.

My career as an athlete has been varied and exciting. I’ve had the privilege of representing my country (Great Britain) as a sledge hockey player at the 2006 winter Paralympics and I won the T42 200m Gold medal at the London Games in 2012, setting a new world record in the process. The years in between I’ve spent training and competing as a distance runner and hold the world record for both the full and half marathons. The most exciting challenge so far, was running across Great Britain, completing 40 marathons in 40 days from John O’Groats to Lands End.

But, sport is about more than winning medals. It’s about being the best you can be. If I can inspire others to believe that anything is possible if you put your mind to it, that’s where the magic happens. I’ve learnt a lot from elite sport and it hasn’t been a straightforward journey. So together with David, we want to help other athletes through performance mindset and lifestyle mentoring to find their own way of achieving their potential.

David ‘Jacko’ Jackson

I’ve been a professional rugby player for some time, playing for Nottingham Rugby Club for 13 years. Now retired from professional sport, I’ve turned my hand to helping other athletes perform their best and reach their potential by joining the oneathlete team. To me, an athlete is anyone who is focused on developing physically and mentally and adopts the performance approach required to do that successfully. I’m passionate about working with athletes, being part of their journey and helping them to achieve their goals.

In addition to a wealth of experience as a professional athlete, I have a Diploma in Sports Psychology. Together with Richard, we provide the performance mindset and lifestyle mentoring service for one athlete. I’m currently working towards becoming a qualified strength and conditioning coach to support Tim with a particular focus on team sport.

(nee Telford)

I qualified from the University of Birmingham in 2004 as a physiotherapist. Having worked in the NHS, overseas and in a sports injury clinic, I gained a broad range of experience before specialising in sports physiotherapy. I’m also currently studying for my Masters in Sports Physiotherapy and am really excited about using this new knowledge to help athletes achieve their goals. I’ve worked with a number of sports at regional, national and international level. These include rugby (union and league), hockey, swimming, athletics, triathlon, cycling and gymnastics. I’ve also worked with GB Canoeing supporting their canoe slalom athletes both at home and when they were competing overseas. I currently also provide sports physiotherapy support for GB Paratriathlon.

My love for sport makes this more than just a job for me; I know one athlete will allow me to push the boundaries of cutting edge physiotherapy techniques and work with individuals who are self-motivated and ready to take control of their own development.
