Love to enter race, wanting an achievement (4,2,5)
I believe the answer is:
tour de force
'an achievement' is the definition.
(tour de force is a kind of achievement)
'love to enter race' is the wordplay.
I cannot quite see how this works, but
'love' could be 'o' (love means zero in tennis) and 'o' is located in the answer.
'to' could be 'for' and 'for' is present in the answer.
This explanation may well be incorrect...
'wanting' acts as a link.
(Other definitions for tour de force that I've seen before include "Skilful achievement" , "Outstanding performance" , "Brilliant work" , "Outstanding feat" , "Masterly or brilliant feat" .)
