Winter Olympian (5)
I believe the answer is:
skier
'winter olympian' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for skier that I've seen before include "High ball; Alpine sportsman" , "Slider on snow" , "Winter sports athlete" , "He glides across snow for fun" , "needs catching on way down" .)
