The 2004 Olympic Games was the only major competition for Moreno in 2004. She did not compete at the World Athletics Final and experienced a foot injury which sidelined her for the first half of 2005. This meant she was dethroned from the leading position at the world ranking, but she recovered the position after a gold medal at the 2005 World Championships and a victory at the 2005 World Athletics Final. For the first time in her career, however, she went a whole season without improving her personal best.
