The problem with this for cardio is keep it up without causing an injury. Sprinting is the surest way to develop an injury for someone not well trained or overweight. What works better (and safer) is running on the treadmill at 15% grade. That gets the heart rate elevated long before you give yourself achiles tendinits or shinsplints or any of the other common runner maladies.
