Rival of S Coe ran and ran desperately (9)
I believe the answer is:
scrambled
'rival of s coe' is the definition.
I can't tell whether this defines the answer.
'ran and ran desperately' is the wordplay.
'ran' becomes 'bled' ('bleed' can be a synonym of 'run').
'and' is a charade indicator (letters next to each other) (I've seen this in other clues).
'ran desperately' becomes 'scram' (I am not sure about this - if you are sure you should believe this answer much more).
'bled' put after 'scram' is 'SCRAMBLED'.
Can you help me to learn more?
(Other definitions for scrambled that I've seen before include "like the RAF officer's eggs?" , "Taken off immediately" , "Haphazardly thrown together" , "Thrown together in a disorderly fashion" , "Made electronic messages unintelligible" .)
