Route information
Click here for the course map.
The CDF 10K takes runners on a sightseeing tour of the city, with highlights including Cardiff Castle, Central Square and the Principality Stadium.
The course journeys through the heart of central Cardiff, before crossing the River Taff and heading towards the leafy suburb of Pontcanna and the grade 2 listed parkland of Llandaff and Pontcanna Fields. Runners then pass Sophia Gardens, the home of Welsh cricket, before passing Cardiff Castle once again ahead of a grandstand finish in the Edwardian Civic Centre. The route is flat and fast, perfect for PB chasers and those new to the distance.
There is also a 2k Fun Run taking place on the day before the main 10k event. All juniors will receive a medal, accompanying adults will only receive a medal and chip timing if they choose the "Fun Run Adult" ticket. If they do not wish to receive these, you can add an accompanying adult pass (£3) in the checkout process for the Child ticket.
