WASD to move, mash X to keep your endurance up, and mash Z to increase your top speed. Go to the yellow line and wait there to start. If you don't, your test will be canceled. (Hint: When you hear the original pacer test audio, you should wait at the line since it's going to start soon) When the pacer test starts, run to the green, then back to the yellow line. Keep doing this as long as you can.
