The Cardiff Half Marathon returns to the Welsh capital on Sunday 6 October, with around 27,000 runners expected to take part.
Now one of Europe's largest half marathons, the theme of this year's Principality Building Society event is 'A Race for Everyone.'
Whether you're taking part in the run itself or spectating from the sidelines, here's all you need to know.

How long is the race?
The full distance is 13.1 miles or in metric 21.1km.
Where is the start line?
The race begins outside Cardiff Castle.
What is the route of the half?
After starting outside the castle, runners will then travel past the Principality and Cardiff City Stadiums. They will then progress onto Penarth passing onto to the Marina and crossing the barrage and then heading to Cardiff Bay.
The course then heads towards the north of the city and runners will complete a loop of the beautiful Roath Park Lake.
Where is the finish?
After passing Roath Park, runners will then head to the finish line outside the Civic Centre in the city on King Edward VII Avenue.
Where can I watch my friends and family who are running the race?
Thousands of spectators are expected to head out and watch their family and friends take part in the race.
The official organisers say those wanting to see their loved ones begin their race should head down Castle Street towards the River Taff for the best view of the start line.
For people wanting views of the closing stages of the race, the advice is to head to Corbett Road from 10:15am. You can also head down to the tiered standing terraces looking over the finish line on King Edward VII Avenue.
Now in its second year, Pride Cymru will also be holding events at the roundabout located between Roath Park and Lake Spice restaurant.
Here runners will pass twice between miles 10 and 12, with the roundabout being the stage for entertainment from well-known drag queens in Cardiff.
