Cycling finishes in sprint, French kind of race (6)
I believe the answer is:
ethnic
'race' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for ethnic that I've seen before include "Relating to a particular cultural group" , "Denoting origin by descent" , "Relating to a cultural tradition" , "To do with race or nationality" , "Characteristic of a human group" .)
