Crossword Genius

Runner in various kinds of winter sports (3)

Ross

I believe the answer is:

ski

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

'runner' is the definition.
(something which 'runs', ie moves quickly on snow)

'various kinds of winter sports' is the wordplay.
'SKI' is hidden within the letters.
However, I'm uncertain how this is indicated.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for ski that I've seen before include "Participate in winter sport" , "Engage in a winter sport" , "runner in winter" , "What one might do in Alps" , "go uphill? Probably not!" .)

I've seen this clue in The Globe and Mail and The Irish Independent.
