Route information
The race starts outside Cardiff Castle and runners then head down past the Principality and Cardiff City Stadiums on the way to Penarth. They take in the glorious Penarth Marina before crossing the barrage and heading to Cardiff Bay. Runners run right through the heart of the bay taking in the Norwegian Church and Wales Millennium Centre.
The course then heads towards the north of the city and runners will complete a loop of the beautiful Roath Park Lake before the grandstand finish in the heart of the city at the Civic Centre.
The predominately flat and fast course makes it ideal for beginners and elites.

What entry category do I fall under for the Principality Cardiff Half Marathon?
Affiliated and Welsh Athletics price types are for those registered with an athletics club – membership numbers must be stated during registration. The General Entry category is for those who are not registered with an athletics club. You will need to provide an up-to-date membership number upon entry so please have this handy and ensure that your club membership is up-to-date.
When will my race pack arrive for the Principality Cardiff Half Marathon?
It will arrive within 7 days of the event at the latest. If you are an Overseas Entrant, you will need to collect it from the Event Village.

How old must I be to take part in the Principality Cardiff Half Marathon?
All runners must be aged 17 or older on the day of the event.
How will my start pen for the Principality Cardiff Half Marathon be allocated?
You will be allocated a pen, depending on your predicted finishing time that you will submit when entering the race. Pen number ranges will vary depending on total competitor entries so therefore pen colours can vary between years, even when the same estimated time is given at point of entry. It is unfortunately not possible to change your allocated start pen, so please take care when completing your entry form to ensure you receive an appropriate allocation. The number of runners in each starting pen is carefully calculated to ensure a safe number of participants are in each, so it will not be possible to move forward into an earlier starting pen. You can however move back if you wish.
