The Chester Triathlon is an Olympic distance triathlon held in the centre of the historic City of Chester. It is currently in its 28th Year. Since 2025 it has been organised by Active Leisure Events who took over organising this fantastic event from Chester Triathlon Club members who organised it for the previous 26 Years. Active Leisure Events continue to work closely with Chester Triathlon Club who support on the delivery.
Take a look at our TV Programme show on Channel 4 from 2015 here.
The Chester Triathlon has been awarded the World Standard Distance Triathlon Qualifier for the Deva Olympic distance which will again race the same course that we have had since 2013. The 100K distance has now become the Deva Centurion – 100K and the new addition in 2025 of the Deva Short Distance will continue again in 2026. We will also once again be including a standard distance Aquabike.
We have had so many fantastic comments about the course being located right in the heart of the City. Transition is in the fabulously stunning Grosvenor Park, a fantastic Victorian Park. The bike route will be a single lap (2 laps for the Deva Centurion – 100K) into Wales via Eccleston, Rossett and Borras and back into Chester via Alford and Boughton. The run route will incorporate running over the Old Dee Bridge as well as the suspension bridge, along the Groves and in the meadows with the finish being at the Bandstand, a truly City Centre race.
Please make sure you have read the British Triathlon Federation Rulebook.
