Fourteen sisters (Seven Sisters round trip)

Hey everyone, I’m planning a day to properly stretch my legs and I stumbled upon the seven sisters hike, about 13 miles in 4-5 hours. I know you can take a bus back but I was thinking about hiking back as well, thus doing a matahon distance. Has anyone done this and can share the experience/give advice? When’s the best time to start, etc. Is the route too ambitious for one day? I’d also appreciate gear related advice, I’m planning on wearing trail runners and a running vest. Thanks.
