We're delighted to be taking part in the Cardiff Half Marathon for its 21st year.

Its flat, fast course passes all of the city’s most breathtaking scenery and iconic landmarks including Cardiff Castle, the Principality Stadium, Civic Centre and stunning Cardiff Bay.

We're very proud of our Welsh branch – Wales was the first UK nation to commit to ending new cases of HIV by 2030.

We have a number of guaranteed places in the Cardiff Half Marathon and we'd love for you to join our team.
