Run through the Welsh capital's most iconic landmarks with beautiful scenery and historic buildings. Starting at Cardiff Castle, passing Cardiff City Stadium, the Penarth Marina, Cardiff Bay, Roath Park Lake and crossing the finish line in the heart of the city at the Civic Centre, take a tour of Cardiff and soak in the incredible atmosphere as you tick off 13.1 miles. The flat and fast course makes it ideal for beginners and elites alike.

The event does allow hand-propelled wheelchair competitors. Please be aware there is a long incline early on at 3 miles and a significant climb at 12 miles for about 300 metres that previous wheelchair participants have found difficult and have had to go up backwards.

You should also be aware that there are a number of speed bumps around the course, including along Penarth Portway in Penarth Marina at the 4 mile point and around Roath Park Lake between the 10-12 mile point. 

Participants taking part in a wheelchair are able to have a complimentary support runner. Please email us at running@macmillan.org.uk if you wish to have a support runner with you. 

By joining us you'll know that you're helping improve the lives of people living with cancer in the UK today.
