MyTriathlon was created in 2008, in the early days of triathlon. Two friends who had begun training together at their local triathlon club went on to race a Sprint distance, followed by an Olympic distance, before finally completing a long distance Triathlon together in Frankfurt –  finishing a mere five minutes apart! Their journey took them to the committee of their local Triathlon Club in Manchester and onto the Boards of British Triathlon and Triathlon England, before they decided to launch their own Triathlon. It was to become the third largest triathlon event in the UK, after both London and Blenheim.

MyTriathlon Retail was initially launched as an answer to an issue that we came across often whilst organising our own event: many entrants simply didn’t want to commit to buying a wetsuit (especially those who believed that their first triathlon would be their last! )

MyTriathlon provides more than 30 different wetsuits and the full Triathlon apparel and accessory ranges from the five most trusted triathlon brands.

With the popularity of triathlons growing year on year, many first timers have obviously, like us, caught the ‘triathlon bug’ and have embarked on their own long distance journeys, the goal that seemed so inconceivable when we first set out.
