In minecraft, effects can make the player run faster than their normal maximum sprinting speed.

What level of speed is required to make the player twice as fast as normal?

I don't think that speed 2 makes you twice as fast, even though it's name would imply such.

According to the Wiki for Speed:

Increases walking speed by 20% × level. Expands field of view (FOV) accordingly.

Therefore, to achieve double the speed, you would need Speed 5 to reach 100% more than the normal rate. You can use the /effect command to obtain this.
