Tour regularly has scrap round route (5)
I believe the answer is:
orbit
'route' is the definition.
(orbit is a kind of route)
'tour regularly has scrap' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'has' says to put letters next to each other.
'scrap' becomes 'bit' (synonyms).
The alternate letters of 'tour' are 'or'.
'or'+'bit'='ORBIT'
'round' is the link.
(Other definitions for orbit that I've seen before include "Field of influence" , "Area of influence - eye socket" , "astronauts' course" , "E.g. planetary movement" , "Circumgyration" .)
