Get back on track in France, impressed by meandering course (7)
I believe the answer is:
refocus
'get back on track' is the definition.
'france impressed by meandering course' is the wordplay.
'france' becomes 'f'.
'impressed by' means one lot of letters goes inside another.
'meandering' is an anagram indicator.
'course' anagrammed gives 'reocus'.
'f' inserted inside 'reocus' is 'REFOCUS'.
'in' acts as a link.
(Other definitions for refocus that I've seen before include "Shift one's attention" , "aim again" , "As photographer may have to" , "regain concentration" , "prepare for another shot" .)
