run

I'm a little stuck... Click here to teach me more about this clue!

'change' is the definition.
(I know that run is a type of damage)

Can you help me to learn more?

(Other definitions for run that I've seen before include "Flow; smuggle (goods)" , "Control" , "trip" , "Jog; manage" , "Dash" .)

I've seen this clue in the Evening Standard.
