Being organised, went quickly (3)
I believe the answer is:
ran
This clue is a double definition.
'being organised' is the first definition.
(run can mean to organise or lead)
'went quickly' is the second definition.
(I've seen this in another clue)
(Other definitions for ran that I've seen before include "Managed; operated" , "Organised" , "Sped" , "Was candidate" , "11 on foot" .)
