The Oysho 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 event has grown significantly since it was founded by Barnardo’s in 2003 when 1,500 runners took part. It now attracts a mass race field of over 27,500 registered runners alongside world-class athletes in a trio of fiercely contested men’s, women’s and wheelchair elite races.
