Beans for athletes? (7)
I believe the answer is:
runners
I believe this clue is a double definition.
'beans' is the first definition.
(runner beans)
'for athletes?' is the second definition.
(runner is a kind of athlete)
(Other definitions for runners that I've seen before include "messengers?" , "Branches from the base of plant that produce new plants" , "Shoots" , "They deliver messages on foot" , "Horizontal branchs that produce new plants" .)
