Near Tumble the trail is closed due to a landslide, so be aware you cannot make it all the way through to crosshands.

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

Park at Rhyslyn and use the cycleway to Afan trails as a useful warm up before hitting the climb or Penhydd or Y Wal

You can enjoy lovely views of the town and Afon Valley from this high up viewpoint on Pontrhydyfen Viaduct. The viaduct itself was build in 1898 by the Port Talbot Railway.
