The stories of the world of ´stayeren´ are beyond imagination and the Dutch are the main cyclists keeping it alive.

In the first decades of the 20th century it was the cycling sport with by far and then some the most spectators and the prize money was higher than today even. It was also rather risky; 60 deaths in 4 decades.

Last Februari he trained for >68 km/h, again in Moscow, with 80 x 12:
