'went speedily' is the definition.
'raced' can be an answer for 'went' (racing is a kind of going). I am not certain of the 'speedily' bit.

'expert in road' is the wordplay.
'expert' becomes 'ace' (ace can informally mean very good).
'in' indicates putting letters inside.
'road' becomes 'rd' (abbreviation for road).
'ace' put within 'rd' is 'RACED'.
