Moreno competed at the first Olympic triathlon at the 2000 Summer Olympics. She was one of two Brazilian athletes, along with Mariana Ohata, not to finish the competition. At the 2004 Summer Olympics, Moreno again competed in the triathlon.[6] Again, she did not finish, making her the only athlete to start in both of the first two Olympic triathlons but finish neither.[citation needed]
In November 2006, Moreno qualified for the Pan American Games in Rio de Janeiro,[7] finishing in ninth place.[8] Four years later, she qualified for her fourth edition of the Pan American Games, but an injury prevented her from competing.[9][10]
