Better to walk at an easy pace in Greece (7)
I believe the answer is:
gambler
'better' is the definition.
(a gambler is someone who bets)
'walk at an easy pace in greece' is the wordplay.
'walk at an easy pace' becomes 'amble' (I've seen this before).
'in' is an insertion indicator.
'greece' becomes 'gr' (abbreviation).
'amble' put within 'gr' is 'GAMBLER'.
'to' is the link.
(Other definitions for gambler that I've seen before include "One who bets" , "Risk-taker" , "Speculator" , "Risk taker" , "one who takes chances!" .)
