A way up a track (6)

I believe the answer is:

ascent

'a way up' is the definition.
(I've seen this before)

'a track' is the wordplay.
'track' becomes 'scent' (both can mean a trace left by someone).
'a'+'scent'='ASCENT'

(Other definitions for ascent that I've seen before include "Upwards motion" , "Upward journey" , "A rise in status; climb" , "rising?" , "Upward slope" .)

I've seen this clue in The Irish Independent.
