Sports sled (4)
I believe the answer is:
luge
'sports sled' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for luge that I've seen before include "Winter sport" , "Glue for a one-man sledge" , "Light toboggan" , "Small sledge for one" , "Racing sled for one or two people" .)
