The Cardiff Half Marathon has evolved into one of the largest and most exciting road races in Europe. As Wales’ biggest mass-participation event, and the second largest half marathon in the UK, this race is the perfect opportunity to challenge yourself while raising money for a great cause.

The fast, flat course takes runners through Cardiff’s most stunning landmarks, including the iconic Cardiff Castle, the Principality Stadium, Civic Centre and beautiful Cardiff Bay. Thousands of spectators line the streets, creating an electric atmosphere in a city known for its sporting passion.

Whether you’re an experienced runner or a first-timer, this race is an unforgettable experience. And, with The Lily Foundation, you can turn your run into a powerful way to support those affected by mitochondrial disease.

The Cardiff Half Marathon is open to anyone aged 17 or above.
