ABOUT US
We are one of the longest running triathlon clubs in the country, originally formed by enthusiasts over 30 years ago.
Our head coach, Martin Darlison, was one of the founders and has a wealth of experience of coaching from novice through to international age group triathletes.
We welcome everyone across all abilities and adult age groups, from absolute beginners to experienced club athletes and GB age-group representatives. Many of us joined after competing in the annual East Grinstead Try-a-Tri race for the first time and found a whole new world of friends, fitness and skills.
To find out more about the club, read about our testimonials below and contact our membership secretary if you have any questions.

MEET THE CHAIR

Tim has been a member of East Grinstead Tri Club since 2011 and has served as Chair since 2024. Over the years, he has competed in a range of sprint and middle-distance triathlons, as well as single-discipline events.
A swimmer at heart, Tim can often be found thrashing up and down the pool. Away from the water, he enjoys cycling, particularly in Mallorca and the South of France, and has taken part in numerous long-distance road and gravel cycling events. Running is not his sport of choice, although he does dust off his running shoes for the very occasional marathon, roughly once a decade.
As Chair, Tim has championed greater club participation in local races and events, while also supporting the club’s popular annual training camps in Mallorca and the South of France. He also plays a key role on the East Grinstead Triathlon Race Committee, helping to deliver the club’s flagship event, which he believes is one of the most important and rewarding parts of club life.
