At the 2008 Summer Olympics in Beijing, Sánchez finished her ranking round with a total of 643 points.
This gave her the 18th seed for the final competition bracket in which she faced Katsiarina Muliuk in the first round.
[2] Sánchez achieved a gold medal in the women's team event at the 2007 Pan American Games alongside Ana Rendón and Sigrid Romero, Colombia's first gold medal in the event at the Games.
She did not compete in the 2011 Games four years later due to a dispute between Sánchez, Rendón, and Romero and the Colombian national coach Kim Hag Yong.
Following the archers' lack of confidence in Kim's training methods and their refusal to work with him, the three were withdrawn from the Games by the Colombian Olympic Committee.
