Pearson rose to prominence in 2001, when at the age of only 14, she won the Australian under-20 100m title. After injury setbacks during 2002 she made her international debut at the 2003 World Youth Championships in Sherbrooke, Canada and won gold in the 100 m hurdles. The following month, still only 16 years old, she represented Australia at open level at the 2003 World Championships in Paris, France as part of the 4 x 100 m relay team. In 2004 she won a bronze in the 100 m at the World Junior Championships, and just missed out on a medal in the 100 m hurdles.

Lolo Jones was born on August 5, 1982. In her youth, Lori "Lolo" Jones had a series of obstacles to overcome. Jones attended eight schools in eight years while her single mother, Lori, often held down two jobs to support her family of six. Lolo's father spent most of her childhood in the Air Force or later in state prison. In third grade, the Jones family settled in the basement of a Des Moines Salvation Army church. During the summer when day camps were offered at the church, Lolo would wake up early to avoid being teased by other kids if they found out she was living in the basement.
