Bolt exposed? (6)
I believe the answer is:
streak
'bolt' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for streak that I've seen before include "Run without clothes" , "Dash (in the nude?)" , "Run naked as stunt" , "series of lucky wins" , "run? Barely!" .)
