One might be for this athletics event (4,4)
I believe the answer is:
high jump
This clue could be a double definition.
'one might be for this athletics' is the first definition.
'high jump' can be an answer for 'athletics' (high jump is a kind of athletics). I'm unsure of the remainder of the definition.
'event' is the second definition.
(high jump is a kind of event)
Can you help me to learn more?
(Other definitions for high jump that I've seen before include "Fosbury's event" , "punishing?" , "Tough punishment" , "Bound" , "expecting to be dressed down?" .)
