Reading Triathlon

Celebrating 40 Years of Triathlon in the UK

Join us on September 3rd 2023 for an historic milestone as we celebrate 40 years since the first ever British Triathlon Championships at our iconic race venue. The Reading Triathlon & Aquathlon was the birthplace of triathlon in the UK, held at the Kirtons Farm Water Sports Centre in 1983. Tri2O Triathlon Club proudly presents the Reading Triathlon, a race organised by triathletes for triathletes.

It has been 40 years since the first ever triathlon in Britain! Global Triathlon Network were in Reading, the site of the race on the 5th of June 1983. So, in a nod to Triathlon reaching middle age, we go back in time to recreate it. Has our kit stood the test of time? Did it change for the better? It’s time for another presenter challenge! 

This year, we’re excited to offer six thrilling race options, including a special one-off route recreating the 1983 British Triathlon Short Course Championships. We’re also making exciting changes to the course, including a revised run route.

Entries are now closed for this year’s Reading Triathlon. There will be no entries on the day.

If you missed out this year we hope to see you next year!

The Reading Triathlon is conveniently located just off the M4 with ample parking. The triathlete-led event team prides itself on its friendly atmosphere and this well-organised event suits beginners and experienced triathletes alike. As a club-run event, our primary focus is the athlete experience; all proceeds from the event are shared between reinvestment in the club to support activities for members, significant donations to charity, and a small contribution to volunteers to say thank you for their efforts. We have decided to support a local sport-focussed charity “Sport in Mind” this year, whose mission is to transform the lives and mental health of children and adults through sport and physical activity.

Entries open before the end of January and are limited to 350 participants, so don’t wait to secure your spot in this historic event. Please note that due to inflationary price increases from our suppliers, ticket prices have slightly increased from last year. However, we’ll be operating a flat pricing system this year, so the price will remain the same until entries close.
