How to capture speed at which on hit event happens?

Hey, I’m using the first person BP and am trying to generate an event if the player hits a wall at a certain speed head on. I’ve already figured out how to check the angle of the hit, but I only want the event to run if the player was at a certain velocity when they hit the wall. My velocity comes out as 0 on hit since the wall stops your movement, so I was wondering if there was a way to capture the characters velocity on the hit before it sets it to 0?

Velocity would always equal 0 on hit I suppose. Instead, get the impulse value.
