Cares about competitions (5)

I believe the answer is:

races

'competitions' is the definition.
(I know this)

'cares about' is the wordplay.
'about' indicates anagramming the letters.
'cares' with letters rearranged gives 'RACES'.

(Other definitions for races that I've seen before include "Sprint and marathon?" , "Speed contests for horses, cars etc" , "Competitions; ethnic groups" , "Running competitions" , "Competitive trials of speed" .)

I've seen this clue in The Globe and Mail and The Irish News.
