Athletics event you wouldn't get over losing (4,4)
I believe the answer is:
high jump
'athletics' is the definition.
(high jump is a kind of athletics)
'event you wouldn't get over losing' is the wordplay.
I cannot really understand how this works, but
'event' could be 'jump' (jump is a kind of event) and 'jump' is present in the answer.
The remaining letters 'high' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for high jump that I've seen before include "Tough punishment" , "Event for the upwardly mobile" , "Dick Fosberry's sport flop or drastic punishment" , "bar activity?" , "If one's for this, it's unfortunate" .)
