ELI5: If I was in a plane travelling just behind the speed of sound, if I ran forwards at the necessary speed, could I break the sound barrier?

No. Breaking the sound barrier requires you going faster than the air around you. As the air in the plane is travelling at the same speed as the plane you could not break the sound barrier by running down the aisle.
