Sinan Osman has been central to my son’s development in the world of Triathlon and I cannot recommend him highly enough. My son has only been involved in the sport from the age of 15, Sinan’s approach has been clear, direct, and highly professional.
He sets clear expectations, provides structured guidance, and makes sure that every session is purposeful and productive.
We’ve had experience with a number of triathlon coaches, and what sets Sinan apart is his ability to balance motivation with discipline. He pushes my son to reach his full potential while maintaining a supportive and encouraging environment. His technical knowledge is outstanding, and he gears his coaching to suit individual strengths and areas for improvement.
Most importantly, Sinan delivers results, my son’s endurance, technique, and overall performance have improved significantly under his guidance. Not only that, but his confidence has also grown, which is a testament to Sinan’s ability to inspire and develop many young athletes.
I’d thoroughly recommend Sinan if you’re looking for a coach who is professional, no-nonsense, and truly committed to getting the best out of his athletes.

What stands out most is his ability to communicate effectively and inspire every athlete. Sinan fosters a culture of excellence that encourages athletes to push their boundaries, all while creating a sense of camaraderie and support amongst the team. His balance between the technical demands of triathlon and the mental and emotional needs of the athletes is exceptional. He understands the importance of resilience, a positive mindset, and self-belief, which has made a real difference in my child’s growth.
Under Sinan’s guidance, my child has become more confident, disciplined, and goal oriented. What I genuinely appreciate is the professional yet approachable nature of Sinan. He maintains open and transparent communication with both athletes and parents, ensuring we are always informed about progress, goals, and challenges along the way.
As a parent, I trust Sinan completely. His passion for triathlon, combined with his exceptional leadership and coaching abilities, makes him the perfect person to coach the next generation of triathletes.

I have known Sinan Osman for 2 years and, simply put, he has had remarkable impact on my daughter’s approach to triathlon. Whilst I anticipated he would provide structure and guidance to her training, I did not expect his immense sensitivity, pragmatism and encouragement around dealing with more sensitive issues such as nutrition and injury.
Most significantly he has instilled a mindset of taking personal responsibility, which has led to her attitude and perspective evolving to the next level. The coaching he gives is first class, as has been his planning, organisation and communication around numerous events and training camp. Thanks to Sinan Osman my daughter believes she can go all the way and as a parent I could ask for nothing more.

Sinan has provided consistently excellent information on training and the broader skills needed to work to be an elite triathlete. He has encouraged our son’s involvement in his development, and we have seen him grow in confidence and ability. We feel he has been provided with really high quality and up-to-date advice on all aspects of triathlon.
Sinan makes himself available for questions, is extremely knowledgeable and organised and the quality of the training opportunities and camps have been fantastic.

For the last 8 months Sinan has been acting as a personal coach for our Son. The improvements that he has seen during this short time have been incredible, particularly regarding his running form and flexibility. But more than that, our son loves having the interaction with Sinan, enjoying his sessions, trusting his advice and expertise. We wholeheartedly endorse Sinan as a fantastic coach.
Sessions are always planned meticulously, the purpose, requirements, expectations of every session couldn’t be clearer. That said, Sinan doesn’t rest on his laurels - he is constantly asking for feedback on everything, striving to make even more improvements to future sessions.

Every session with Sinan is a delight for both my son, his father and myself. Actively engaged in and enthusiastic about my son’s development, Sinan eagerly takes the time to communicate and discuss one on one how training can be more meaningful and productive, adapting to my son’s needs when required.
Sinan’s goals and targets for training are unique to my son, as they are based on his unique statistics, and Sinan reflects constructively with my son upon his race days. Sinan’s support of both my son’s mental health and his passion for achievement in sport has curated a strong, happy, and proud athlete. Due to this, Sinan is deeply respected and loved by my son and the other athletes, and he has fostered a safe and encouraging community. We cannot thank him enough.

We’d known Sinan for many years before he became our son’s 1:1 coach and hadn’t really realised the benefits it would bring. 2 years later and we wouldn’t hesitate to recommend Sinan as a 1:1 coach.
Our son is very independent, driven and committed to triathlon - Sinan has guided him, helped him and worked with him to become a coachable, open and successful young athlete. The two of them have worked together, meaning we could step back knowing our son was in very safe, capable hands, and leaving us to concentrate on being parents. The triathlon journey brings lots of fantastic opportunities, but is very rarely smooth - so the guidance we have received from Sinan has been invaluable.

Sinan was my coach from 2019 to the end of the 2022 competition season. I received so much guidance, support and really beneficial training sessions from Sinan during this time, which ultimately led me to have a great 2022 racing season where I competed at both the Junior European Triathlon Championships [elite] (and finished 10th), and in the Junior World Triathlon Championships [elite].
Sinan was an attentive coach who prioritised both my mental and physical wellbeing, really focussed on goal-driven training, and I felt completely comfortable talking to him about any female-specific training issues. This was a really important and valued aspect of our coaching dynamic, especially since Sinan was my coach during my developmental age as an athlete and I think this made a huge impact on how I performed.

Sinan has coached our son for over 12 months before he headed to university.
When he started coaching, my son was suffering with a ‘back injury’. With that in mind, Sinan worked with him and concentrated on what he could do, focussing on swimming and cycling. Running at that point was not possible.
They worked together to agree goals and targets, and built a bespoke training program that was reviewed and developed over time.
Despite the difficulties of his injury, Sinan kept our son motivated and with a structured training plan which resulted in him achieving PB’s in his swimming and significant improvements in power output on the bike.
They developed a strong working relationship and a mutual respect for each other.
We highly recommend Sinan as a coach and thank him for his hard work and dedication to helping our son keep his dreams alive.
