The clear round I would contest (7)
I believe the answer is:
evident
'the clear' is the definition.
(I've seen this before)
'round i would contest' is the wordplay.
'round' is an insertion indicator.
'i would' becomes 'I'd'.
'contest' becomes 'event' (event can mean a sporting competition).
'id' put inside 'event' is 'EVIDENT'.
(Other definitions for evident that I've seen before include "Quite obvious and clear" , "Conspicuous" , "Clear to see" , "Readily apparent" , "Incontrovertible" .)
