Hurry in Athens, travelling around (6)
I believe the answer is:
hasten
'hurry' is the definition.
(I know that hurry can be written as hasten)
'athens travelling around' is the wordplay.
'travelling around' indicates anagramming the letters.
'athens' anagrammed gives 'HASTEN'.
'in' acts as a link.
(Other definitions for hasten that I've seen before include "Hurry up in old-fashioned way" , "Make faster" , "Hurry along" , "Act or move fast" , "Athens (anag.)" .)
