**Extensive Road Closures Announced in Cardiff for Spectacular Weekend Triathlon**
Cardiff is once again preparing for a major sporting event this weekend, as thousands of athletes descend upon the city for the highly anticipated Cardiff Bay Triathlon, taking place on Sunday, 22 June 2025. Organisers, Always Aim High Events, promise dynamic races and an electric atmosphere as both seasoned and amateur triathletes tackle courses winding through some of the capital’s most iconic waterside locations.
With race day on the horizon, local authorities have outlined significant road closures to ensure both participants and spectators can safely enjoy the festivities. Residents, commuters and businesses are strongly encouraged to familiarise themselves with these restrictions, which will have a notable impact on traffic flow in parts of Cardiff Bay and surrounding areas from the early hours of Sunday.
Preparations for setting up the triathlon will commence the preceding day, Saturday, 21 June. However, no road closures are scheduled for Saturday itself, with all shutdowns coming into effect from before dawn on race day. Roads will be closed in stages depending on the race progress, with different durations outlined for specific stretches.
The triathlon offers four race categories—super-sprint, sprint, standard and legend (middle distance)—all revolving around the vibrant surroundings of Cardiff Bay. During last year’s event, crowds lined the route, and organisers are hoping to repeat the buoyant, supportive atmosphere for the 2025 edition. The standard route is particularly popular, starting with a 1,500 metre swim in Cardiff Bay’s freshwater, closely monitored by safety personnel in boats. Participants will then set out on their cycles for three laps, each covering 13km of characterised flat terrain on closed city roads, with highlights including the Wales Millennium Centre and Cardiff International Sports Village.
After the cycle segment, competitors complete the final phase with a two-lap run. This picturesque course takes runners past landmarks such as the Norwegian Church and the Barrage, looping back towards the finish line beside the Millennium Centre. The combined challenge of swimming, cycling, and running tests even the most experienced triathletes, many of whom cross the finish line exhausted yet exhilarated.
To accommodate the triathlon, several major roads will be closed to traffic. The following closures are scheduled between 5:15am and 10:30am on Sunday:
– International Drive from the junction with Olympian Drive
– Olympian Drive, Watkiss Way, and Dunleavy Drive (from Watkiss Way to Dunleavy Drive Retail Park)
These closures are extended until 1:30pm for other crucial thoroughfares, including:
– East Tyndall Street from Schooner Way to Herbert Street and Lloyd George Avenue
– Lloyd George Avenue, between Herbert Street and Bute Place (with limited access for residents, managed by stewards)
– Bute Place, from Lloyd George Avenue to Pierhead Street
– James Street, Clarence Road, Avondale Road, and Ferry Road up to Clive Street
Spectators are warmly invited to enjoy the spectacle, particularly from Cardiff Bay, which provides excellent vantage points to see every stage of the race—from the dramatic swim starts and fast-paced bike transitions to the inspiring final run. Those attending are advised to arrive early and plan routes accordingly.
For drivers and local residents, event stewards will be stationed at strategic points to help guide traffic and ensure smooth access where possible. Cardiff Council urges anyone travelling through the area to consider alternative routes and heed the advice of on-the-ground teams and advance communications.
With the triathlon expected to bring vibrant crowds and a festive environment once again, Cardiff is eager to showcase its status as a top sporting destination. As the event draws nearer, up-to-date information can be found via local websites and official event channels, ensuring everyone can prepare for a safe and memorable Cardiff Bay Triathlon weekend.
