Instructors going out to the races (8)
I believe the answer is:
teachers
'instructors' is the definition.
(I know this)
'going out to the races' is the wordplay.
'going out' indicates an anagram (out can mean wrong or inaccurate).
'the'+'races'='theraces'
'theraces' anagrammed gives 'TEACHERS'.
(Other definitions for teachers that I've seen before include "beaks?" , "Instructors" , "Coaches" , "Lecturers" , "They impart knowledge" .)
