The information below relates to the 2021 event on Sunday 26 September.

With a mixture of nerves and excitement riding high, please take time to make sure you’re familiar with the important event instructions:

Time & Location
Sunday 26 September 2021. 8:00am – 2:00pm, Roald Dahl Plass, Cardiff Bay. The 10K begins at 10:00am, and the Family Fun Run at 1:00pm.

Travel & Parking
Cardiff Bay is easily accessible by car, foot or public transport. It’s a 20-minute walk from the city centre and is served by regular buses and trains (via Cardiff Queen Street). Parking is available in County Hall for £5 all day. Public transport and car parks will be very busy on race day, so please arrive early to avoid missing the start of the race. Visit or for more information.

Please be aware that Cardiff City will be playing Chelsea at the Cardiff City Stadium at 14:05 on race day. The roads will be particularly busy from 11:00, so please allow more time for travel in case the road network is busy.

Race Number
Enclosed in your race pack was your running bib, with a unique race number. It’s vital that you keep this safe as a timing chip (which enables us to give you your finishing time) is embedded into all 10K race numbers – which cannot be reissued. Please pin the number to the front of your t-shirt on race day, and remember to complete the medical information on the back of your race number. This is VERY important.

Bag storage is situated behind the Pierhead Building, and will be open from 8:00am. Tear off the baggage label strip on the bottom of your 10K race number and attach it to your bag before you arrive.

10K Race Start

The 10K race starts on the Northbound Carriageway of Lloyd George Avenue, near Roald Dahl Plass. This is a NEW start location, due to COVID-19 safety precautions. The solid colour behind the number of your running bib will dictate which pen you must assemble in before the race. Pens will open at 09:45am for a 10:00am start.

2K Race Start
The 2K Family Fun Run will begin at 1:00pm from the start line in the Roald Dahl Plass in Cardiff Bay, in front of the Wales Millennium Centre. Under 8s must be accompanied by an adult.

Be sure to arrive in time for the official 2K warm up, led by This Mum Runs Cardiff ‘Run Angels’, starting at 09:45am.

Health and Safety
Our 10K route takes place on fully closed roads, but competitors should be aware of their surroundings and listen out for marshal’s instructions for their own health and safety. Trip hazards, such as speed bumps will be clearly signposted but please keep an eye out!
