The Cardiff University/Cardiff Half Marathon is one of the UK’s largest road races and attracts more than 20,000 runners and 50,000 spectators to the city.

From the elite field – which attracts some of the world’s top runners – to the club athletes and charity fun runners who raised more than £2.4million in 2015, the race has something for everyone.

The event is known for its fantastic atmosphere and support and it could not be staged without the tremendous support of the residents and businesses of Cardiff.

We try our utmost to minimise any disruption that may be caused. Full road closure details and more information on the 2016 race will be available in due course. Please return to this page ahead of race day for full information on road closures and suggested routes in and out of the city.

Road Closures:

For maps guiding you in and out of the city, please consult our road closure page, here:

  • 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
