Hardly moves fast on journey? Quite the opposite here! (4,5)

'quite the opposite here' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'hardly moves fast on journey?' is the wordplay.
I cannot quite understand how this works, but
'journey?' could be 'trip' (trip is a kind of journey) and 'trip' is found in the answer.
The remaining letters 'drags' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
