Teller gets changed to run race (9)
I believe the answer is:
raconteur
'teller' is the definition.
(term for a storyteller)
'changed to run race' is the wordplay.
'changed' indicates anagramming the letters.
'to'+'run'+'race'='torunrace'
'torunrace' anagrammed gives 'RACONTEUR'.
'gets' is the link.
(Other definitions for raconteur that I've seen before include "Skilful teller of anecdotes" , "source of stories?" , "one with a gift for relation" , "A skilled story teller" , "source of anecdotes" .)
