Track is definitely one of the best sports to represent all different laws and different parts of physics. Discus and shot-put represent a projectile projector because after it is thrown it creates a probably having a mass and velocity before hitting the ground. The speed of a runner is determined by the distance traveled with each stride. It is also easy to figure out how much distance a runner will cover in a given time that the coach tells them. When having the velocity at which they are traveling we use the following equation: V=d/t, if we rearrange that equation and plug in velocity and time (vt=d) we will get the distance the runner should get with the given time.
