Races, or rips (5)
I believe the answer is:
tears
I believe this is a double definition.
'races' is the first definition.
(tearing is a kind of racing)
'rips' is the second definition.
('tear' can be a synonym of 'rip')
(Other definitions for tears that I've seen before include "Lacrimal drops" , "Shed them in sadness" , "Signs of unhappiness" , "Rips with signs of sorrow" , "Rips; droplets" .)
