Way, course (5)
I believe the answer is:
route
This clue is a double definition.
'way' is the first definition.
(route is a kind of way)
'course' is the second definition.
(I've seen this before)
(Other definitions for route that I've seen before include "Choice of roads in an itinerary" , "Path to follow" , "Course followed" , "Course, road" , "Course of journey" .)
