Run various trips round capital of Norway (6)
I believe the answer is:
sprint
'run' is the definition.
(sprinting is a kind of running)
'various trips round capital of norway' is the wordplay.
'various' is an anagram indicator.
'round' is an insertion indicator.
'capital of' indicates taking the first letters.
The first letter of 'norway' is 'n'.
'trips' with letters rearranged gives 'sprit'.
'sprit' placed around 'n' is 'SPRINT'.
(Other definitions for sprint that I've seen before include "Run rapidly" , "Short race at full speed" , "quick run" , "Run at full speed for a short distance" , "Rush" .)
