The Principality Cardiff Half Marathon has grown into the UK's second largest half marathon and now is a member of the SuperHalfs, a global series of the world’s most prestigious races.
On this flat, fast 13.1 mile course you'll pass the city’s best scenery and most iconic landmarks including Cardiff Castle, the Principality Stadium, Civic Centre and stunning Cardiff Bay!
Join us and make a real difference to the cats and kittens that need our help.
Please note, this event has now sold out for 2025. Please contact our team to be added to our waiting list or to register your interest for 2026.
For this half marathon there is a £10 registration fee and we ask for a minimum sponsorship commitment of £250.
This amount could pay for an operation on a shattered leg or a procedure to remove a cancerous lump, helping to reduce suffering for a cat in distress and pain.
Join our team of Cat Champions to get a Cats Protection running vest, then simply set up a fundraising page and raise whatever you can to help the cats and kittens.
It was an amazing day, the crowd were behind all participants and having my name on the vest helped as there were typical calls of 'come on Linda, do it for the cats!'
