Sprinting champion Edward ran fast (6)
I believe the answer is:
bolted
'fast' is the definition.
(synonyms)
'sprinting champion edward ran' is the wordplay.
I cannot quite see how this works, but
'edward' could be 'ted' and 'ted' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bolted that I've seen before include "Fastened door with sliding bar (6)" , "Absconded" , "Fled, having locked up?" , "Ran away" .)
