Manage to move at speed (3)
I believe the answer is:
run
I believe this is a double definition.
'manage' is the first definition.
(both can mean to organise)
'move at speed' is the second definition.
(to run is to move fast)
'to' is the link.
(Other definitions for run that I've seen before include "Manage (eg, a company)" , "Proceed quickly" , "Move quickly; smuggle" , "athletic event" , "Card sequence in suit" .)
