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

A lovely cafe and bar on the sea front. They do lovely coffee and the food is great too. Great place to stop when you’re going for a walk on the beach! Dogs are allowed and there’s indoor and outdoor seating
