My friend is running the marathon this Sunday. What's the best way to get to the start in SI when coming from Port Washington? LIRR to the city, then subway to the ferry to SI? His start time is 10:40am, wave 3.

If this were for me I would have had this planned out awhile ago lol and it's actually giving me anxiety that he's just figuring this out now.

Appreciate any help you can provide, thank you!!
