The course takes runners toward the Brangwyn Hall, along The Kingsway and onto High Street, back toward Swansea Castle, then onto Princess Way and Victoria Road before returning to Oystermouth Road. The final turn is at Knab Rock, followed by the Promenade toward Blackpill Lane and the finishing straight. It says runners get 5 miles of views across Swansea Bay and calls it one of the flattest half marathons in the UK.
