The track is 4000 km long, and passes all big
cols in the French mountain areas. The ride is done individulally, but
participants may take as long as they wish to accomplish the complete
About 2000 participants were registered since 1979 when the tour first started. Only 500 of them really succeeded in doing the job.
Most of our riders (from The Netherlands, Belgium, UK, France, Switzerland, USA, Canada, Australia and more), agree that there is nothing compared to the beauty of the 100 Cols route.
Since the original release in 1979 the route is much improved, sometimes drastically. In 1983 a.o. the Couillole, Bonette and Grand Colombier were added to the route. The second big change took place in 1989, when almost 1000 km were changed because of the heavy traffic on many roads. At this change the Marie Blanque and Ballon d' Alsace were added. Haguenau became the new startingpoint in stead of Wissembourg, that already had replaced Bitche in 1983. In 1996 Saverne, near Strasbourg, replaced Haguenau again as the startingpoint.
Since 1992 every two years the route and its itinerary are improved, as we search alternatives for less suitable roads. In 2005 an extra track in the Pays Basque was included in the route with the Burdincurutcheta and the Soudet.
Almost 3000 km of the original release has been replaced now.
