The Cardiff Half Marathon has grown into one of the largest and most exciting road races in Europe. It is Wales’ largest mass-participation and multi-charity fundraising event and the second largest half in the UK. Its flat, fast course passes all the city’s most breath-taking scenery and iconic landmarks including Cardiff Castle, the Principality Stadium, Civic Centre and stunning Cardiff Bay. Thousands of spectators turn out to cheer on the runners in a city renowned for its sporting passion.
The Ellen MacArthur Cancer Trust inspires young people aged 8-24 to believe in a brighter future living through and beyond cancer through sailing and outdoor adventure.
For many young people simply picking up where they left off before their diagnosis just isn’t possible. So, when treatment ends the Trust’s work begins.
