Cardiff Half Marathon

Sunday 6 October 2024

The 21st edition of the Principality Cardiff Half Marathon will take place on 6 October in 2024. Demand is at unprecedented levels after the success of our bumper 20th-anniversary edition in 2023 and a big increase in demand from overseas runners.

Cardiff is a part of the SuperHalfs which includes races in Prague, Berlin, Lisbon, Copenhagen and Valencia. Finishing the race will earn you a stamp in your SuperPassport and count towards completing the series.

Registration for 2024 is now open. We’re anticipating our earliest ever sell-out, with all 5,000 discounted early bird entries selling out within just 3 hours of going on sale. The race is now on to secure one of our remaining general entries before it’s too late!

Run for Charity

Charity is at the heart of the Cardiff Half – where many will be raising money for fantastic good causes. Knowing your run has helped others gives 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 our 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 selecting ‘View All Charities’ below. You can also use your own space and opt to use it to run for charity.
