Background and career

In the 2004 Summer Olympics, she won a bronze medal in the cycling women's points race, the first Colombian to win a medal in cycling. She was initially stripped of the medal after a positive test result for the banned stimulant heptaminol. However, the medal was reinstated after the test result was proven incorrect.
On October 16, 2011, at the 2011 Pan American Games' individual time trial, Calle, 43 years old at the time, won the gold medal with a time of 28:04.82.
On 22 July 2015, it was disclosed that she had tested positive for GHRP2 at the 2015 Pan American Games and was subsequently banned for four years.
