Cardiff Half Marathon

Familiarise yourself with all of the important race day information

For details on additional measures that will be in place to protect runners, volunteers and the wider public from COVID-19 please click here.

Please note that the majority of the information below is for the 2019 race! We will update this page with 2022 race day information in the lead up to the event.

Race Time

The Cardiff University Cardiff Half Marathon will start from 10:00am on Sunday 27 March & Sunday 3 October in 2022 on Castle Street.

The race has a staggered start to ensure all runners cross the start line as safely as possible. The White, Red and Green start is at 10:00am and the Yellow and Blue start is at 10:10am.

Late starters will not be permitted to take part.

Running Number and Timing Chip

A timing chip will be embedded in your running number. Please remember to bring it with you on the day as these cannot be reissued. Make sure your number is pinned to the FRONT of your vest or t-shirt. Failure to wear your number across the start line will mean your time will not be recorded.


It is against race rules to swap your bib number with any other runner outside of our official transfer service. Each bib number has unique emergency contact and health details attached digitally, so swaps lead to medical teams working off incorrect information on the day which can have serious consequences – including invalidating insurance. Systems are in place to monitor this and those found to be swapping numbers will be banned from all future Run 4 Wales events. 

Timing Pens

The solid background colour of your race bib (either white, green, red, blue or yellow) will correspond with a coloured starting pen and race start time. Please assemble at the back of your colour-coded pens via the clearly indicated coloured flags. The start map on page 12 explains how to get to your coloured pen. For safety reasons, runners must assemble in the correct colour start pen and cannot move forwards a pen, only backwards.

Please allow enough time to walk to the start and assemble. White, red and green pens will open at 09:15am, with yellow and blue pens loading later at 09:40am. If you’re in the yellow and blue pens, remember that the start is just a short walk from the Event Village, so why not spend some time soaking up the atmosphere there before heading to your pen at 09:40am.

The race will have a staggered start to ensure all runners cross the start line as safely as possible. Each runner will be provided with a chip and gun finish time. Your gun time will begin when the starting ‘gun’ is fired at the beginning of each pen start. Your chip time begins as the chip timing on your running number passes over the starting line.

Please note, the white pen is further sub-divided into elite and sub 1:30 areas on the morning according to your race number and predicted time.

Baggage Area

The baggage tents will be open at 8.30am. They are located on Museum Avenue and in the museum car park near the Runners’ Village. Please refer to the village and baggage map in this brochure for an exact location. All runners are allowed to deposit one bag which must display your baggage label, which is a tear-off strip on the bottom of your race number. Please attach the label before your arrival. Bags can be collected after the race upon receipt of your runner number. Bag checks will be in operation. We suggest joining the queue to check in your bag by 09:00 at the latest.

Items not collected after baggage closure will be held at the Event Information tent in the Runners’ Village. The following day they will be taken to the Run 4 Wales offices. Please contact the events team to arrange collection at [email protected] or on 029 2166 0790. It is strongly advised that you leave valuables at home. Race organisers cannot be held responsible if items go missing or are damaged. We will do our utmost to safeguard your baggage, but the area is not secured.

Presentation Ceremony

The prize ceremony will take place at 11.30am near the finish line. Prizes will be awarded to race winners.

Finish Line and Commemorative Items

After finishing the race please continue moving through the finish line and post-finish area to collect your commemorative items (medal, water, and bananas) to avoid congestion. Medical staff will be on hand for anyone who feels unwell or needs medical attention. After the finish line all runners will receive a t-shirt, medal, water, banana and other items.

Your t-shirts available between XS and 3XL sizes will be given out to the ratio of sizes requested at point of entry, therefore we cannot guarantee that your requested size will be available if others who finish ahead of you change their mind on the day. We kindly ask all participants to collect the size they requested.

Toilet Facilities

There will be several banks of toilets around the Civic Centre in the Event Village and on the way to the start, including:

– On King Edward VII Avenue, outside the Law Courts
– On Boulevard de Nantes, outside the Law Courts
– Near the starting pens

There will be several toilets positioned within the first mile and at each water station (urination on the street will result in disqualification and a ban from the event in the future). Race officials will be monitoring for offender.

Lost Property & Unwanted Clothes

There will be a lost property point situated at the Event Information point in the Event Village. Beyond race weekend, please contact the events team at [email protected] or on 029 2166 0790. Where possible, please avoid leaving clothes at the start. Any unwanted clothes left behind will be donated to charity.

Cut-off Time and Road Re-Opening

This year’s event carries a 4.5 hour cut off time, to ensure roads can safely re-open within a reasonable time frame to minimise impact on the city. If runners fall behind the pace required to finish in this time, a sweep vehicle will collect them. Runners wishing to continue must do so on the pavements as roads will be re-opening. You do so at your own risk and will no longer be a part of the event.

The course will be signposted from this point and volunteer marshals will ensure the safe crossing of junctions.

Your Safety

If at any time during the race you feel unable to continue, please stop, rest and locate the nearest marshal for advice. Medical teams will be on hand around the course, as well as at the start and finish areas. There is comprehensive medical provision around the course and across the event venue. If you require treatment on the day, you will be taken to the event medical centre located directly after the finish line. If you have a minor injury our walk-in medical facility is located in the Event Village. Next of kin looking for an injured runner should report to Event Information in the Event Village to be given further instruction.

IT IS VITAL that you ensure the medical information on the back of your runner number has been completed. It is your responsibility to inform the organisers if you have any special medical conditions.

In the unlikely event of any major incident, the Race Director and Emergency Services have the right to:

  • Alter or shorten the route, but still provide a race if possible
  • Stop the race at any time if deemed necessary

This would be in circumstances beyond the control of race organisers and no refundswould be given.
