Road Closures for the Cardiff Half Marathon

On Sunday October 2nd, one of the top endurance races in the UK, the annual Cardiff Half Marathon returns to the streets of Cardiff.

The race will involve more than 20,000 runners from all over the world and it is also Wales’s largest fundraising event with over £2.4 million raised for over 800 different charities and causes. The new start time for the race is 10.00am. The race will be broadcast live on BBC Wales television and radio.

Due to the nature of this event, a number of road closures will be in place on race day. As such, a number of usually busy roads will be closed, including Lake Road West, Lake Road East, Cathays Terrace, Richmond Road, Albany Road, Ninian Road, and sections of Castle Terrace in the city centre.

The organisers of the Cardiff Half Marathon recommend taking these steps on race day:

  • Please allow for extra time when travelling on race day.
  • Open access routes (indicated in green) will be open at all times during the day. Please aim for these when navigating around the city.
  • Please take note of the road opening times indicated on the map. Many roads used by the course will be open within one or two hours of the start of the race at 9am. This will subsequently open up large areas of the city.
  • Plan your route in advance and be aware of potentially congested areas.
  • Be careful in areas of shared road use (as indicated on the map). This is where the race route directly meets open roads.
  • If you have any queries or concerns about any of the road closures detailed, please email or phone 02921 660790
