Twisty race (6)
I believe the answer is:
slalom
'twisty race' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for slalom that I've seen before include "Downhill skiing race" , "Skiing obstacle race" , "Downhill race over a winding course on skis" , "Ski racing event" , "Ski race down zig-zag course" .)
