Run old-fashioned English course (5)
I believe the answer is:
route
'course' is the definition.
(I've seen this before)
'run old-fashioned english' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'old-fashioned' becomes 'out' (as opposed to 'in').
'english' becomes 'e' (abbreviation).
'r'+'out'+'e'='ROUTE'
(Other definitions for route that I've seen before include "Established line of trave" , "Regular journey" , "Established line of travel" , "Way travelled" , "Course of journey" .)
