Movement is the essence of life.

Every morning in Africa, an antelope wakes up. It knows it must outrun the fastest lion, or it will be killed.

Running is perhaps the most fundamental of all sports, and it is economically the least costly to perform. As a consequence, it is the most democratic and most competitive of all sports because individual merit can prevail despite economic equality. It is a sport for everyone, the whole world over.

The essential thing is to run period!And to do it for a long time and consistently and then everything will take care of itself.
