People rush along (4)
I believe the answer is:
race
I believe this is a double definition.
'people' is the first definition.
(people can mean a national group or race)
'rush along' is the second definition.
(I know that rush along can be written as race)
(Other definitions for race that I've seen before include "Breed" , "Stock" , "The ... is not to the swift (Bible)" , "Career - people" , "Run swiftly" .)
