Hare's competition in a fable (8)
I believe the answer is:
tortoise
(Other definitions for tortoise that I've seen before include "Lettuce-munching plodder" , "This creature might turn to Tories" , "Mobile home owner?" , "Slow-moving reptile that won race against a hare" , "Slow-moving four-footed reptile - outraced the hare" .)
