'no doubt about force going' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'wrong way' is the wordplay.
'wrong' becomes 'off' (I've seen this in other clues).
'way' becomes 'course' (course is a kind of way**).
'off'+'course'='OFF COURSE'

Can you help me to learn more?

(Other definitions for off course that I've seen before include "A slice may put one thus" , "Drifting" .)

I've seen this clue in The Telegraph.
