Manage to make haste (3)
I believe the answer is:
run
This clue is a triple definition!
'manage' is the first definition.
(I've seen this before)
'to make' is the second definition.
(thesaurus)
'haste' is the third definition.

(Other definitions for run that I've seen before include "Organize" , "Path made by animals" , "Manage; flee" , "politician must do this to get elected" , "Uninterrupted sequence" .)
