Sprints And Marathons
Running is the act by which animals, including human beings, move by the power of the feet. Speeds may vary and range from jogging to a sprint. A lot of individuals compete in track events that place participants in a contest to test speed in a sprint or endurance in a marathon. The running mechanics are the same, but additional factors are very different in a marathon versus a sprint.
