I believe the answer is:

skier

I'm a little stuck... Click here to teach me more about this clue!

'sportsman?' is the definition.
(someone who skis)

I don't understand how the remainder of the clue works.

(Other definitions for skier that I've seen before include "needs catching on way down" , "Sportsman who glides over snow" , "Winter sports athlete" , "High ball; Alpine sportsman" , "he's possibly going downhill quickly" .)

I've seen this clue in the Evening Standard.
