Chance to abandon golf for a leisurely walk (5)
I believe the answer is:
amble
'a leisurely walk' is the definition.
(casual or relaxed walk)
'chance to abandon golf' is the wordplay.
'chance' becomes 'gamble' (gamble can mean to risk or chance).
'to abandon' indicates named letters should be taken away.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'gamble' with 'g' taken away is 'AMBLE'.
'for' is the link.
(Other definitions for amble that I've seen before include "Meander" , "Walk gently" , "Blame for leisurely walk" , "Make slow progress" , "Move at an easy pace" .)
