Sport in which runners are stood on? (6)
I believe the answer is:
skiing
'sport' is the definition.
(I know that Skiing is a type of winter sport)
'in which runners are stood on?' is the wordplay.
I cannot really understand how this works, but
'in' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for skiing that I've seen before include "Gliding over snow" , "Travelling over snow on runners" , "Winter sports" , "Mountain sport" , "Participating in a winter sport" .)
