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

'the race' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'crazy uncle rob and me up' is the wordplay.
'crazy' indicates anagramming the letters.
'and' says to put letters next to each other.
'uncle'+'rob'='unclerob'
'unclerob' with letters rearranged gives 'lbournec'.
'lbournec' after 'me' is 'melbournec'.
'melbournec'+'up'='MELBOURNE CUP'

'for' acts as a link.
