Jon Warren   4performanceuk

I am a coach who is here to support athletes through their triathlon, duathlon, running and fitness journey. I have a passion in working with athletes who are looking to step up either in terms of performance or distance. With a young family and full time job, I understand the pressures involved with work, family and social commitment. Therefore, I develop a time efficient plan which fits around your personal circumstance taking these factors into account. Please do not hesitate to get in touch.


I currently work with all levels of ability from beginner to advanced age group athletes. I am Head Run Coach for Havering Triathlon Club and also Head Tri Coach for 4performanceuk.
I have competed in triathlon since 2012 across various distance and have achieved noticeable success in Long and Ultra Distance events.
I have both competed in and coached athletes to GB Age Group level.
Qualified British Triathlon Federation Level 2 Diploma Coach.
