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 short climb up from the road brings you to the Dam and carpark, there is no access over the Dam itself. But you do get a good view over the spillway and valley below.
