Manage to stand, stretch, exercise and give a lift to ladder (3)
I believe the answer is:
run
This clue is a sextuple definition!!!
'manage' is the first definition.
(both can mean to organise)
'to stand' is the second definition.
(as in to stand or run for election)
'stretch' is the third definition.
(run can mean to stretch or extend over an area)
'exercise' is the fourth definition.
(running is a type of exercise)
'and' acts as a link.
'give a lift to' is the fifth definition.
(to run someone somewhere is to give them a lift)
'ladder' is the sixth definition.
(both can mean a tear in tights)
(Other definitions for run that I've seen before include "publish" , "Move at speed" , "A point scored in cricket" , "On the . . . - fleeing from pursuit" , "journey" .)
