Boring people run without hurdles (4,4)
I believe the answer is:
flat race
'run without hurdles' is the definition.
I can't tell whether this defines the answer.
'boring people' is the wordplay.
'boring' becomes 'flat' (flat can mean dull or lifeless).
'people' becomes 'race' (people can mean a national group or race).
'flat'+'race'='FLAT-RACE'
Can you help me to learn more?
(Other definitions for flat race that I've seen before include "Derby, for example" , "St Leger, for instance" , "The rush, of course" , "event" , "not hurdled" .)
