Run As Fast As You Possibly Can!
To run really fast, I suggest you do this with radical highway. First,
do a spin dash. Then,as soon as Shadow rolls in a ball, immediatley
press the b button. He then will stop rolling, stop moving his feet,
tilt his head,and running at a dangerously fast speed. NOTE:Do this
downhill and over a speed boost to run even faster. This can also
work well with Sonic running from the truck in city escape.
