Typical flat race (7)
I believe the answer is:
classic
I believe this is a double definition.
'typical' is the first definition.
(thesaurus)
'flat race' is the second definition.
(I've seen this before)
(Other definitions for classic that I've seen before include "Eg, screw thread" , "Creation of the highest standard" , "Great piece of creative writing" , "Serving as a standard - of the highest quality" , "Of the highest order - the Derby, for example" .)
