American visiting prostitutes returned for obstacle race (6)
I believe the answer is:
slalom
'obstacle race' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for slalom that I've seen before include "Skiing obstacle race" , "Type of ski race" , "Downhill ski event" , "Ski racing event" , "Winter Olympic event" .)
