Join us at the Cardiff Half Marathon! Since it was founded in 2003, the Principality Building Society Cardiff Half Marathon has established itself as one of the UK’s leading road races.
The route takes in all of the cities most iconic landmarks including the Principality Stadium, Cardiff Bay, the Civic Centre and Cardiff Castle. Thousands of spectators turn out to cheer on the runners in a city renowned for its sporting passion.
Every day, 34 people in the UK are given a devastating brain tumour diagnosis. For these people and their loved ones, cures simply can’t wait! When you sign up to take on the Cardiff Half Marathon every mile you run, every metre you move and every penny you raise, will help give hope to those affected by brain tumours.
Every £300 you raise
could fund a day of world-class research into brain tumours.
Every £1,000 you raise
could fund the RNA sequencing required for one of our research projects developing cures for children with brain tumours for an entire year.
Every £2,000 you raise
could fund the bioluminesence imaging required for a year on one of our glioblastoma research projects.

You must complete all six races within 60 months, starting from the date you finish your first race. “Complete” means you must finish the race, i.e. you must have an official chip time in the race results. Runners can complete the races in any order.
-
If successful, you will also need to pay a £35 registration fee per half marathon application. A member of our Events Team will contact you to arrange. Successful applicants will need to arrange their own travel and accommodation.
The minimum fundraising target is £350 per half marathon exclusive of any registration fees.
-
SuperPassport is your digital passport where you can collect stamps as you complete each race and track your progress on your running journey. It shows your official race results. It doesn’t show our race registrations.
You will need to input this passport number whenever you enter a race. You can create your SuperPassport (your SuperHalfs account) with its unique passport number at www.superhalfs.com. If you have entered your SuperHalfs passport number on the registration form when you signed up for any of the races, your passport will be automatically stamped within three days after the race. If you did not insert a SuperPassport number, you will be able to claim your result in your SuperHalfs account a few days after the event. We always send an email confirmation to all SuperPassport holders when the results are added or ready to claim. Once you are registered for your final race with your passport number, the race organisers will be notified that you are expected to attend and become a SuperRunner – meaning your SuperMedal will be ready for collection once you have crossed the finish line.
