New beachfront course and city-wide traffic measures
The annual Swansea Bay 10k returns this Sunday, 20 September, marking its 45th anniversary with a revised course along the city’s seafront. Organisers say the altered route will give runners the chance to take in the coastal views as they make their way from Guildhall Road South towards the Mumbles and back along the Prom.
To facilitate the event, Swansea Council has announced a programme of road closures, traffic diversions and parking restrictions across key parts of the city. Officials have confirmed that access for emergency vehicles will be maintained at all times, but motorists, public transport users and local businesses are being advised to plan journeys in advance as congestion is expected.
Route details and timing
The revised course will begin on Guildhall Road South, follow the road down towards the Mumbles and reach the 5k point shortly after Norton Avenue. Runners will return to Guildhall Road South along the Swansea Prom. The flat, scenic course has long been popular with local and visiting runners.
Road closures and restrictions
Council notices set out specific closures and times. Key restrictions include:
- Saturday 19 September, 12:00–23:59: Guildhall Road South, both directions from filter lane to junction with St Helen’s Road (Crown Courts)
- Sunday 20 September, 00:00–17:00: Guildhall Road South, both directions from its junction with Brynamor Road and Beach Street; Francis Street and Guildhall Road North 05:00–17:00
- Sunday 20 September, 08:00–17:00: St Helen’s Crescent
- Mumbles Road closures in both directions from Argyle Street to Sketty Lane with specified allowances for some turns and car park egress

What this means for residents and visitors
Residents living along the route should expect restricted vehicular access during the closure windows and may experience noise and increased foot traffic. Local businesses on or near the promenade and the Mumbles Road corridor should anticipate a larger number of visitors but also possible disruption for supplier deliveries and customer access.
"Those attending the event or planning to travel around Swansea this weekend are advised to plan their journey ahead of time to avoid delays," the event guidance states.
Public transport users should check services for temporary diversions or altered timetables. Where possible, organisers recommend using sustainable travel modes such as walking, cycling or public transport to reach the city centre on race day. Car drivers are urged to allow extra time, follow signed diversions and respect temporary parking restrictions to help keep roads clear for participants and emergency access.
For many in Swansea the 10k is a highlight on the calendar — an opportunity to celebrate community spirit along our coastline. The move to a seafront route underlines the city’s coastal identity, but it also brings practical consequences that residents and visitors should factor into weekend plans.
Further updates and detailed maps of the route and closures are available from Swansea Council and the event organisers’ information pages. Anyone with mobility concerns or who requires special access should contact the council ahead of the weekend to confirm arrangements.
