Henry James
I'm currently racing as a professional triathlete, with experience at national and international level in Triathlon and Duathlon over the last 10 years. I've raced all distances from sprint to Ironman as both as age grouper and professional whilst balancing this with full time work. This has given me a wealth of knowledge to share with athletes I coach. Seeing the athletes we coach progress and achieve what they set out to do is highly rewarding, giving people the platform to exceed what they ever thought was possible.
My Role
I founded Proven Performance Coaching in 2020 with the goal of sharing our Triathlon and endurance sports expertise to help others. I'm experienced in training design, tapering and race preparation, tactical/technical aspects of racing, equipment choices, and more. With a strong understanding of optimising training under time constraints for Triathletes who don't have the luxury of unlimited training hours.
I am our triathlon and running coach based in Cheltenham, Gloucestershire, having a valuable network of local complimentary service providers and which enables me to make referrals as required. If you are local, 1:1 coaching sessions can be arranged.
Tom Hartwell
Undertaking a coaching scholarship whilst part of the University of Leeds Cycling Club has led me into supporting many athletes; my pursuit of coaching now enables me to share my passion for cycling and endurance sport.
I personally race all disciplines of cycling, and have strong backgrounds in Road and MTB. This translates into my coaching as I always endorse getting stuck into races, and trying different events to find weakness' we can work on.
My Role
I've been coaching athletes for three years, with a mix of physical and technical preparation. I put a focus on working closely with athletes to make sure they can achieve the goals we set out and perform to the highest level possible.
David James
I'm a former Modern Pentathlete, having competed at three Junior World Championships and been team manager for the elite squads. I've worked in high performance sport for many years, most recently holding an executive role at the University of Gloucestershire.
I'm a professor in sports and exercise science, with expertise in endurance and multi-disciplinary sport. I have a PhD in Exercise Physiology, having published widely on respiratory and cardiovascular physiology, athlete assessment and training science.
My Role
I contribute to the training science that all our coaches use with the athletes, forming the bread and butter of the training plans, and undertake athletes physiological assessments (Lactate Testing). I consult with athletes, providing innovative training guidance based on current evidence and results of their assessments/performances. I lead the evaluation of our approaches, ensuring our athletes get the best possible experience and outcomes.
Gwen & Sean Kinsey
I (Gwen) raced to Scottish national level at swimming as a youngster, however converted to Modern Pentathlon after finding a love for riding horses. This led to a highly successful professional career winning the British Junior Championships, competing at Senior World and European Championships, winning a relay gold medal in Budapest in 1999, and silver in Pesaro in 2000. More recently I have competed in Triathlon with many age group World and European titles. I am super passionate about helping others in their journey, now being a British Triathlon Level 1 coach, with multiple years of experience.
I (Sean) have swam to a high level all my life, my greatest achievement as a youngster was finishing 5th in the National 1500m Championships! Over the years I've competed internationally across Modern Pentathlon, Biathle, Aquathlon, and Masters swimming. I've had a more recent open water speciality as this is my passion, winning multiple masters medals at the open water championships. I am a Swim England Level 2 open water swimming coach, Swim England Assistant Coach at our local swimming club (currently training to become a full coach), and British Triathlon Group Coach, all enabling me to use my technical and tactical knowledge to help others.
