Route description
Route description
This route is the perfect tour of Cardiff, taking runners past the city's most iconic landmarks, beautiful scenery, and historic buildings.
The predominately flat and fast course makes this an ideal event for beginners and elites.
The Half Marathon starts outside Cardiff Castle and travels down past Cardiff City Stadium on the way to Penarth. Runners will get to take in the glorious Penarth Marina before crossing the barrage and heading to Cardiff Bay. The route takes runners right through the heart of the bay, taking in the Norwegian Church and Wales Millennium Centre along the way.
The route's last leg takes runners north of the city, to run around the stunning Roath Park Lake before getting their photo finish back in the heart of the city.
Schedule:
08:30 Bag Drop opens
10:00 Half Marathon Starts
11:30 Prize Ceremony Starts
14:30 Cut-Off Time
Runners will be set off in a staggered start, with Red, White, and Green runners starting at 10am, and Blue and Yellow runners starting at 10:10am.
Spectators are more than welcome and help lend to the superb atmosphere of this event.
With thousands of supporters coming out each year, a dedicated spectator zone, and excellent standing terraces, this event is just as special for spectators as it is for runners.
Make sure to arrive in plenty of time to grab the best spot to watch your athlete cross that finish line!
