Good route for a long-distance driver (7)

'good route' is the definition.
'fairway' can be an answer for 'route' (fairway is a kind of route). I am unsure of the 'good' bit.

'a long-distance driver' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'distance' could be 'way' (way is a kind of distance) and 'way' is found in the answer.
The remaining letters 'fir' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'for' is the link.

Can you help me to learn more?
