Egan Bernal sealed the inaugural Colombia Oro y Paz title with a stunning late attack on the final day in Manizales.
The 21 year old and his Dogma F10 hit out three kilometres from the finish and, helped by the brilliant Tao Geoghegan Hart and Sebastian Henao, stayed clear of the chasing favourites to seal the title by just nine seconds.
Having crossed the line second on the stage, behind Dayer Quintana (Movistar), Bernal faced an agonising wait to see if he had done enough - and he wasn't disappointed.
Rigoberto Uran (EF Education First-Drapac) led the favourites home 11 seconds later to confirm Bernal's victory. Sergio Henao finished with Uran and fellow contender Nairo Quintana (Movistar) to wrap up fourth overall, while Bernal also claimed the young rider's jersey.
Speaking before stepping onto the podium Bernal said: “I felt very good all day long and I kept telling the guys: ‘I feel good, I feel good!’ but I had to keep calm and wait for the tougher last kilometres.
“The last three or four kilometres were tougher and I decided to attack. I was fourth on GC so I didn’t have a lot to lose but I had everything to gain.
“I tried, I gave everything and finally I got a little advantage. I had two teammates in the break and they did an amazing job! I was telling Tao: ‘Tao, Tao, it’s so hard, you have to slow down!’ He helped me almost until the last metres.
“The most important thing was to win the GC and not the stage. Of course, it would have been better to win both but the idea was to win the GC. So, my teammates waited for my attack. That’s why I feel so proud and happy with this team. They supported me and did incredible work.”
