Doug Stewart TMR Coaching

“Working with Doug was a huge change: I could share both successes and struggles while we worked together for the same vision. He adapts and understands my journey and has coached me to a very successful year in my career. I find myself fitter, more motivated, and more prepared than ever for the next chapter. ”

– Robert Hajnal, Professional Ultra-Runner, 2022 Winner of Istria 100 by UTMB, Top 10 at Lavaredo Ultra Trail and UTMB Mont Blanc 2022

He’s also helped triathletes qualify for the Xtri World Series Championship (Norseman) and Ironman 70.3 World Championships.

He’s applied the same successful coaching approach to non-elite athletes, leading to 100% finish rate of runners achieving their goals at the UTMB Mont Blanc, Marathon des Sables and other major races worldwide.

Doug has completed a series of coaching qualifications, including: UESCA Certification in Ultrarunning Coaching, IRONMAN U Certified Coach, accreditations with TrainingPeaks Level 2, English Athletics and British Triathlon. He also holds the TrainingPeaks Power Certification qualification and makes use of the latest analytic software for athletes using power data, such as WKO5 and BestBikeSplit.

Doug received his MSc. in Performance Coaching from the University of Stirling. As of October 2022, he is a PhD candidate at Loughborough University in the UK, studying endurance performance and the athlete-coach relationship in a remote setting. He is also the Founder and Performance Director for the Elite Trail Team.

Doug’s coaching advice has been featured in UK and US running magazines and on TrainingPeaks’ blog. His article on UTMB featured in the 2019 Athletes’ Choice Awards.

Outside coaching, Doug has completed some of the toughest mountain running and trail running races, ultramarathons and triathlons on the planet, including the UTMB, the Spine Race, Celtman Xtreme Triathlon, Swissman Xtreme Triathlon and Swedeman Xtreme Triathlon. He also enjoys competing in Skyrunning races and short and technical mountain challenges.


george blackwell

George Blackwell trail and ultra running coach, triathlon coach

George is a Paralympic Centre Assistant Coach within British Paratriathlon's Elite Training Hub at Loughborough University, where he is also a Sports Science student and coaches within the university's triathlon and athletics programmes. He works with a range of abilities, with some athletes simply looking to complete their first competitive race, while others looking to win national medals at British Universities Competitions and earn international representation for GB at Junior and U23 Levels.

George’s approach with athletes is person centred, orientated around what they want from the sport, their coach and their training. He combines these factors to find a tailored, sustainable routine that leaves athletes happy day to day and satisfied with their progression.

He also takes pride in his knowledge of exercise physiology and sees reviewing training data as a pivotal part of informing the training he sets for any individual, using heart rate, power and any other metrics available to make each programme as specific as possible to each athlete. 

George holds multiple coaching certifications, including British Triathlon Level 1 and Level 2, England Athletics Coaching, TrainingPeaks Level 2, and NFCE Level 2 Counselling Skills.

As for his own training, George has a keen interest in all distances and styles of racing within triathlon and distance running, but especially trail and ultra distance races. He’s a proud Manxman, growing up running on the Manx Hills which is fundamental to his passion for trail running. He competes in long distance races and his current main goal is setting a Fastest Known Time attempt at the Raad Ny Follian, the 98 mile coastal footpath of the Isle of Man.

Fun fact: George’s first sporting passion was actually rugby, where he represented Scotland at both U16 and U19 levels.
