Swansea is getting set to host one of its biggest sporting events once again next month as Ironman 70.3 returns to the city. The event will be held on Sunday, July 14, with thousands of athletes getting set to take on the mammoth endurance event.

It will begin with a 1.2-mile, or 1.9km, swim starting at the Prince of Wales Dock before participants will take on a 56-mile (90km) bike course through Mumbles, along roads that hug the Gower’s coastal clifftops, ahead of cycling out through rural Swansea and along Swansea Bay into the city.

Athletes will then take on a 13.1-mile (21.1km) two-loop run which takes them from the city centre, out past the Swansea Arena, towards Mumbles before heading back towards the finish line at the Marina. For the latest Swansea news sign up to our newsletter here.
