despite being a n00b, the running I have done has wielded the result that naturally, when I want to stop I begin to take small, rapid steps, generally lifting my legs higher and leaning back slightly.
Each small step lets you change a small amount of the forward momentum which you had into upwards momentum, whilst leaning back decreases the amount of momentum which is transferred forwards by changing the angle of contact between the pad and the ground, reducing the forward component.
This is, for me at least, a natural response with some basic (potentially incorrect) mechanics applied.
