Its hard to believe but physics is most definitely relevant when it comes to running. While running you have an acceleration as well as an Initial velocity and a final velocity. If you were running around the block and wanted to find out your distance you could use kinematic equations. As long as you have the velocity you started running at as well as the velocity that you ended with. You will also need to know the time or your acceleration to find out your distance. But physics is present greatly while running also due to the fact that you are in motion and also due to the fact that gravity is acting on you as well.
