Where skiers may be missing foremost run (4)
I believe the answer is:
lope
'run' is the definition.
(I know that lope is a more specific form of run)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lope that I've seen before include "Move with long strides" , "Run with a long stride" , "Run along easily" , "Slow pace" , "Stride along" .)
