Motorists and bus passengers across south Pembrokeshire are being advised to prepare for a series of road closures and transport changes as the Long Course Weekend returns to the region this weekend.
The popular endurance event, which draws thousands of athletes and spectators each year, will bring temporary disruptions to routes in and around Tenby on Saturday 28th and Sunday 29th June as competitors take part in the Wales Sportive and Wales Marathon.
Saturday 28th June – Wales Sportive
On Saturday, the Wales Sportive cycle event will see several roads in the wider Tenby area closed or converted to one-way systems to ensure participant safety. While the A40, A477, and the A478 Narberth to Kilgetty routes remain unaffected and fully open, other roads will be subject to closures and diversions throughout the day.

Sunday 29th June – Wales Marathon
Further closures will be in place on Sunday during the Wales Marathon, affecting routes between Tenby and Pembroke. These will operate on a rolling basis between 9.30am and 4pm, with the aim of minimising disruption while maintaining safety for runners and spectators.

Up-to-date information on all road closures can be found on the event’s official website:
