- 100 Cols
The famous route "100 Cols Tocht" was introduced in 1979 by the NTFU (Nederlandse Toer Fiets Unie, the Dutch sport cycling association). Immediately there was a lot of interest. Shortly afterwards in a turbulent episode, they stopped their interference, until a few members from the Utrecht cycling club RTC De Domstad decided to do the route and adapted it over the years. In 1983 the first issue of the route by RTC De Domstad was published.
In 2003 the 100 Cols was further taken care of by the Hundred Cols Foundation.
