Athlete's manager, perhaps (6)

I believe the answer is:

runner

I'm a little stuck... Click here to teach me more about this clue!

'athlete's' is the definition.
(type of athlete)

I can't explain the remainder of the clue.

(Other definitions for runner that I've seen before include "Horse (in a race); bean plant" , "Green vegetable" , "Smuggler; a bean" , "Kind of bean is a fast mover" , "-- bean, vegetable" .)

I've seen this clue in The Times.
