The Marina is a great place to run. It is really flat and you can run past all the boats along the paths. The beach is close by and there are cafes and pubs that you can start or finish it. There's also public toilets there and there is a nice 5k loop or more

Great place to go running. You can run along the beach or there is a path that runs parallel to the beach which is flat and wide enough for runners.

Enjoy unobstructed views across Swansea Beach on this long flat section of paved path that follows the coastline. On a clear day you should be able to see all the way over to Mumbles Head, which marks the start of the Gower Peninsula.
