Massive local crowds flocked to watch their Colombian heroes, and eight out of the top 10 overall didn't disappoint.
Especially Quintana. The Movistar rider gave them plenty to cheer about as he overcame an entanglement with a spectator, who tripped in front of he and Sosa, three kilometres from the finish.
While Sky's new recruit was untroubled by the incident and quickly joined Lopez to leave their fellow Colombian for dead, Quintana placed a foot on the ground to avoid falling himself.
But as the pair failed to cooperate further up the climb as only mere seconds separated them from overall victory, Quintana pounced, crossing the line in front of a rapturous throng for his 40th UCI win.
"The love and passion of the fans and all the cheer I had from them all day gave me that final bit of energy I needed to launch the final attack and take the victory," Quintana who finished ninth overall said.
"The incident with the spectator? It's an analogy of life. It happens sometimes - you stumble, you fall down, you've got to get back on your feet, rise again and keep fighting to win. That's what we did today. It's a victory full of emotions, a day of big happiness, a day when we really worked hard together with the rest of the team, who kept me calm for the entire race.
"It's also a celebration I want to share with all Colombians, all Latin people, those who came over from abroad to meet this region, and especially those from here - stay happy, continue to enjoy cycling. Hopefully events like these can live on and prosper!"
