The details
The Cardiff Half Marathon has grown into one of the largest and most exciting road races in the United Kingdom; and is truly a Race For Everyone. It is now one of Europe’s largest half marathons and is Wales’ largest mass participation and multi-charity fundraising event.
The route takes runners past the capital’s most iconic landmarks with beautiful scenery and historic buildings. It’s predominately flat and fast, making it ideal for beginners and elites.
