Activity in which the participants bow (7)
I believe the answer is:
'activity' is the definition.
(archery is a kind of activity)
'the participants bow' is the wordplay.
I cannot quite understand how this works, but
'bow' could be 'archer' (I've seen this before) and 'archer' is present in the answer.
A single letter 'y' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'in which' acts as a link.
Can you help me to learn more?
(Other definitions for archery that I've seen before include "Toxophily" , "Bowman's sport" , "Sport of the bowman" , "Bowmanship" , "Target sport - Olympic event in from 1900-08, in 1920 and since 1972" .)
