Wales' biggest road race course has been revealed after the International Association of Athletics Federations (IAAF) approved Cardiff's 2016 World Half Marathon Championships route.
Around 200 of the world's best athletes and up to 25,000 amateur runners will race 13.1 miles on Saturday, 26 March.
The route will start outside Cardiff Castle and finish on King Edward VII Avenue in the city centre.
Runners will pass the Millennium Stadium, Cardiff City Stadium, Penarth Marina, the Cardiff Bay Barrage, the Wales Millennium Centre and Roath Park Lake before a grandstand finish in the heart of the capital.
Cardiff has hosted an annual half marathon since 2003 and it is hoped the World Half Marathon will provide another boost for the city's racing reputation.
