Since its inception in 2003, the event has grown into one of Europe’s leading half marathons, attracting a strong field of elite athletes as well as thousands of amateur runners. The race is known for its flat and fast course, its route surrounded by historic landmarks, and its significant role as a fundraising platform for charities.
History and Development
The Cardiff Half Marathon was first organized in 2003 by the charity Barnardo’s, with only 1,500 runners participating. Over the years, the event has seen rapid growth and today hosts approximately 27,500 registered participants annually, making it the largest mass participation sporting event in Wales and a major fundraising platform supporting numerous charities. The race hosted the IAAF World Half Marathon Championships in 2016 and the Commonwealth Half Marathon Championships in 2018. Due to the COVID-19 pandemic, the event was held virtually in 2020 and 2021.
