Like this, running RAF until now (4,3)
I believe the answer is:
thus far
'until now' is the definition.
(both can mean up to the current time)
'like this running raf' is the wordplay.
'like this' becomes 'thus' (I've seen this before).
'running' is an anagram indicator (the letters run around to different places).
'raf' with letters rearranged gives 'far'.
'thus'+'far'='THUS FAR'
(Other definitions for thus far that I've seen before include "'Up to now (4,3)'" , "Up to this point" .)
