Past one's peak? (4,3,4)

I believe the answer is:

over the hill

'past one's peak?' is the definition.
(both can mean advanced in age)

This is the entire clue.

(Other definitions for over the hill that I've seen before include "generally declining" , "past one's prime" , "Getting on" , "as 20 [OLD MAID]" , "walk up and down here?" .)

I've seen this clue in The Times.
