Got over there cycling at the same time (8)
I believe the answer is:
together
'at the same time' is the definition.
('together' can be a synonym of 'at the same time')
'got over there cycling' is the wordplay.
'over' says the letters should be written backwards.
'cycling' indicates an anagram.
'got' in reverse letter order is 'tog'.
'there' with letters rearranged gives 'ether'.
'tog'+'ether'='TOGETHER'
(Other definitions for together that I've seen before include "Appearing as a couple" , "United; in agreement" , "Level-headed" , "in league" , "Collected" .)
