One runs with scoop, originally going to press (8)
I believe the answer is:
sprinter
'one' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for sprinter that I've seen before include "Fast runner" , "speedy runner" , "one in the 100 metres" , "One runs a short distance at top speed" , "Short-distance runner" .)
