In contest surpass inaccurate people (7)

I believe the answer is:

outrace

'in contest surpass' is the definition.
(to outrace is to surpass in a racing contest)

'inaccurate people' is the wordplay.
'inaccurate' becomes 'out' (eg a calculation might be 'out').
'people' becomes 'race' (people can mean a national group or race).
'out'+'race'='OUTRACE'

I've seen this clue in The Times.
