It looks like people have no idea about the popularity of cycling in Colombia.
La Vuelta a España started in 1935. La Vuelta a Colombia started in 1951. For a lot of the years until the present day we even had had 2 to 2.5 weeks of hard racing in the mountains. And let me tell you about the crouds. Without Europeans people go to the street in masses. And even without marketing.

Just think about what a little marketing and some Europens teams can do to the crouds in Colombia. Remember Duitama 1995. The crouds were spectacular. In the 80's before the Pro-Tour almost killed our beloved cycling we attracted quite a few stars to Colombia. The trainning in high altitude worked for a lot of them: Lemond, Hampsten, Hinault, Fignon, Pascal Simon.
I am not saying making it equal to the GT in Europe, but give it a little support, do some fine tunning, some marketing, better broadcasting, shorten it a little bit and you'll have an excellent environment for a race. This would probably has to be at the beginning of the year.
These are some pictures of our traditional Vuelta a Colombia:

"Esta es una imagen de 1963 y corresponde a una etapa conocida como Doble a la Unión..."
"La vuelta a Colombia 1959 "intenta" salir de Pereira hacia Cali."
A classic battle in the Mountains: ... Pacho Rodriguez,Patrocinio Jimenez,Henry Cardenas, Argemiro Bohorquez, Alfonso Florez....Vuelta a Colombia 1979....
Patrocinio rode in the first Tour de France in 1983 and was 17th I think. Alfonso Florez won "Tour de L'avenir" in 1980. All of them became pro's in the 80's.
More crouds awaiting for the riders to come.
And you thought there was no cycling euforia in Colombia. I can assure you that the crouds would go crazy with a good marketed Vuelta a Colombia.
