Hurry to get lessons on track (10)
I believe the answer is:
racecourse
'track' is the definition.
(I know that track can be written as racecourse)
'hurry to get lessons on' is the wordplay.
'hurry' becomes 'race' (synonyms).
'to' is a charade indicator (letters next to each other).
'get' is a charade indicator (letters next to each other).
'lessons' becomes 'course' (a course has lessons).
'on' says to put letters next to each other.
'race'+'course'='RACECOURSE'
(Other definitions for racecourse that I've seen before include "Doncaster, for example?" , "Where to find better" , "Eg, Aintree" , "better frequented location?" , "Venue for meeting" .)
