...His career was cut short when his name was linked by Spanish media to the Puerto blood doping ring. Botero denied the allegations and he was later cleared following a probe by the Colombian cycling federation in late 2006, but he could never returned with a major European team.
“I was in the best moment of my career. I left with this regret. I didn’t even want to look for a team. I don’t know if I could have found a team, because I didn’t even look,” he said. “My best years were at Kelme. In Telekom I had a health problem due to a biopsy they did on my liver, which left with me a big hematoma that was slow to be absorbed.
I started to feel better at Phonak, above all at the Olympic Games in Athens. From June 2006 to February 2007, I couldn’t race because of Operación Puerto. After that, I’ve continued in Colombia. This all [cycling] ends, just like everything in life.”
