Race to get changed early (5)
I believe the answer is:
relay
'race' is the definition.
(relay race)
'changed early' is the wordplay.
'changed' is an anagram indicator.
'early' anagrammed gives 'RELAY'.
'to get' is the link.
(Other definitions for relay that I've seen before include "Hand, pass on" , "article in bank" , "Pass on - put down again" , "Receive and pass on - race" , "Team of workers" .)
