Bertoli qualified for the 2008 Summer Olympics in Beijing, where she competed in women"s modern pentathlon, along with her teammate Claudia Corsini. She managed to improve her performance in the show jumping segment, but dropped to thirty-fourth position, when her horse Naonao repeatedly knocked off numerous obstacles, and suddenly fell her into the ground. In the end, Bertoli finished the event with cross-country running in thirty-second place, for a total score of 4,956 points.
She won two medals, silver and bronze, in the women"s relay event at the 2002 and 2004 World Championships in San Francisco, California, United States and in Warsaw, Poland, respectively. During the competition, Bertoli struggled to attain a higher position in the early rounds, with poor scores in pistol shooting, in one-touch épée fencing, and in freestyle swimming.
Bertoli is a member of the modern pentathlon team for Gruppo Sportivo Fiamme Azzurre, and is coached and trained by Luigi Filipponi.
