Anyone know how to create a streak when running super fast? (Simular to the flash)

Hey! I am new to the unreal engine and I am very interested in how you can create a streak when someone is running super fast. I want to create a character with super speed and I would love to know how to get a streak when that character is running. It is basically the red streak that the flash has.

Thank you!
