The 22nd edition of the Cardiff Half Marathon will take place on 5 October in 2025.
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.
The event always sells out early, but with unprecedented demand from across the UK and overseas, all general entries for the 2025 race sold out at record pace – within just 12 hours of going on sale!
All hope is not lost if you want to run in 2025! You can still secure a space via our official charities and tour operators, or via a Business Challenge package.
Missed out in 2025? Make sure you’ve pre-registered so you’re first to hear when the 2026 event launches!

Run for Charity
Fundraising is at the heart of the Cardiff Half – with many runners choosing to raise money for good causes and over 100 official charities associated with the event. Running for a good cause will give a huge boost to the satisfaction you’ll feel on finishing the race – and keep you motivated during your training.
We encourage runners to fundraise for Lead Charity Partner the NSPCC, or one of our Associate Charity Partners – but it’s up to you!
#TeamNSPCC runners will receive a personalised training plan, training day with expert coaches, a Facebook community to share training tips and experiences with and post-race reception! You can register to run for the NSPCC for just £10 when pledging to raise £300.
Alzheimer’s Society, Cancer Research Wales and Mind are our Associate Charity Partners and offer a reduced entry fee amongst a number of benefits in return for a race space.
A full list of our official charities can be seen by clicking below. You can also use your own space and opt to use it to run for any charity of your choice.
If you are interested in taking on the SuperHalfs Series, don’t forget to create a free passport and insert your passport number when registering for the race!
