The finish of the race occurs as the torso of the player reaches the vertical plane running
exactly on to the inner margin of the finishing line.

WHAT IS THE MEANING OF A STEP?
A step is the distance covered when you take one step. The distance your left foot travelled is your
step length.
WHAT IS THE MEANING OF A STRIDE?
Stride length s the distance covered when you take two steps, one with each foot. Stride length is the
distance from the toe of your right foot (starting position) to the toe of your left foot.
EACH RUNNING STRIDE COMPROMISES TWO PHASES
1. support phase
2. flight phase
support phase can be broken down into two further phases.
1. front support phase
2. drive phase
