And what happens if he didn´t tell the truth about his 1.500m time? Are you telling the truth here all the time with different nicknames? I don´t think so...
We are not debating about his running potential, we are sharing training ideas and systems for each type of runner. Read and analize interval training and repetition training because I think you don´t know the difference between those 2. After that, we can share how to use each one for different type of runners. Some type of runners need more interval training and others need more repetition training.
In america runners are afraid to take long rest between repetitions but doing that are limiting their potential. What´s more important, to run faster and achieve a greater stimulus or to limit the rest and run slower? That´s the secret, open your minds.
Example: -3x2000m/3´-4´ rest , easy walk -3x2000m/200m jog recovery
The first example will be faster than the second and thanks to the rest will be easier to recover in the next days, your hormonal and nervous system will absorb better.
