Travel & Parking
Cardiff Bay is easily accessible by foot, bike, car, bus and train (via Cardiff Queen Street). To embrace a sustainable event, we encourage active travel such as walking or cycling (the city has many accessible cycle routes). 

There are very limited parking options in Cardiff Bay because of the road closures in place for the event, so car sharing is encouraged, and we recommend parking in the city centre (which is a short 1-mile walk or warm up jog from the Bay).

For those arriving by bike, there will be a free bike park available at the top of Roald Dahl Plass outside the Wales Millennium Centre, opposite the water tower.

Bag storage is situated behind the Pierhead Building, and will be open from 9:00am. Tear of 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 10km race starts on the Northbound Carriageway of Lloyd George Avenue, near Roald Dahl Plass. The solid colour (either white, green, red, blue or yellow) behind the number on your running bib will dictate which starting pen you must assemble in before the race.

To avoid confusion on the day it is vital that you look at the Venue Map in the Race Day Guide (below) for details on how to access your starting pen. Pens will open at 10:45am.

Junior Races

The Cardiff Bay Run Junior will commence from 09:45 with the Future Challengers Mile, with the 2K Fun Run at 10:00, followed by the Toddler Dash at 10:40. Races will start and finish in the Roald Dahl Plass.
