Some Filipinos I'd ambitiously backed for cycling event (7)
I believe the answer is:
madison
'cycling event' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'some filipinos i'd ambitiously backed' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'backed' shows that the letters should be reversed in order.
'nosidam' is hidden within 'filipinos id ambitiously'.
'nosidam' written backwards gives 'MADISON'.
'for' is the link.
Can you help me to learn more?
(Other definitions for madison that I've seen before include "4th president of the US - capital of Wisconsin" , "dance?" , "-- Avenue, New York's advertising district" , "James, fourth US president" , "US president - New York square with gardens" .)
