Lightning? Run! (4)

Ross

I believe the answer is:

bolt

I believe this is a double definition.

'lightning?' is the first definition.
(I know that bolt is a type of lightning)

'run' is the second definition.
(I know that bolt is a type of fly)

(Other definitions for bolt that I've seen before include "Leave suddenly and in a hurry" , "Run away; bar of lock" , "From the blue, it's a great surprise" , "wolf" , "Runner" .)

I've seen this clue in The Globe and Mail.
