Control race (3)
I believe the answer is:
run
I believe this clue is a double definition.
'control' is the first definition.
(thesaurus)
'race' is the second definition.
(run is a kind of race)
(Other definitions for run that I've seen before include "Drive" , "Move fast or manage" , "Could be an extra" , "Control" , "Compete in race or election" .)
