Incredible, but true. During the post-War decade from 1946 to 1956, the immortal runner ran 50,000 miles during his training. Who else is entitled to the supreme honour of being called the "Czechoslovakian train."
Brave he was, courageous he was, soulful he was, spontaneous he was. Therefore, it was possible for him to cover such frightening distances. Scientist he never was, but a new vision dawned on him. Therefore, he was able to be the pioneer runner in interval training.
