New York runner, for one, acquires Trojan? (4,5)

I believe the answer is:

east river

I'm a little stuck... Click here to teach me more about this clue!

'new york' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'runner for one acquires trojan?' is the wordplay.
'runner' becomes 'ea' (I've seen this in other clues).
'for' is a charade indicator (letters next to each other).
'one acquires trojan?' becomes 'striver' (I am not sure about this - if you are sure you should believe this answer much more).
'ea'+'striver'='EAST RIVER'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
