Raced round, worried (5)
I believe the answer is:
cared
'worried' is the definition.
'raced round' is the wordplay.
'round' indicates an anagram.
'raced' anagrammed gives 'CARED'.
(Other definitions for cared that I've seen before include "Was concerned" , "Felt concern or interest" , "had feelings" , "Tended" , "Felt affection (for)" .)
