When we talk bang for the buck, sprints have to rank near the top of the list of things you can do that will noticeably improve your distance running in a short time period. From improving your coordination to developing stride power, just a small amount of sprinting can take your running to the next level in only a few weeks. They can be magical, but they can also be disastrous, however. The range of motion required and your body's ability to tolerate huge amounts of force determine if you should even try sprinting in the first place.
