25 kilometers is a long walk. 40 kilometers is a very long walk. 150 kilometers is a very very long walk. Walking 450 kilometers is something that no one can do. Except 7 athletes, who walked this distance in less than 3 days. I went to see them. Here you can see Jean-Marie Rouault after 420 kilometers walking. Colmar is in sight after the vineyards hills, the Sisters of the Holy Solex are good angels.



Paris-Colmar is the oldest (1926) and the longest walking competition in the world. It used to be the 3rd biggest sport event in France. The most crazy one I've heard of, was 5000 kilometers long: crossing the USA.
