Oysho Cardiff Half Marathon
🏃♂️ 21 km
🌍 INT
With unprecedented growth in recent years, and much higher demand than the number of spaces available (the 2025 race sold out in a matter of hours), a Ballot has been introduced for 2026 to ensure fairness for all.
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 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.
Cardiff is a part of the SuperHalfs. Finishing the race will earn you a stamp in your SuperPassport and count towards completing the series of races in Lisbon, Prague, Berlin, Copenhagen and Valencia.
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.
