She won a bronze medal at the 1999 Pan American Games in Winnipeg, Manitoba, Canada,[1] and a bronze and a silver at the 1995 Mar del Plata Pan American Games in the 5,000m and 10,000m respectively.

[citation needed] She won the gold medal in the 2002 Commonwealth Games in Manchester[1] and often refers to this race as the highlight of her career.

[citation needed] Montgomery considered her triathlon career as a full-time "job", and thus competed in very few track races.

She was also selected to compete in the 10,000 meters on the track, but had to withdraw due to injury sustained in the triathlon crash.

[1] Four years later, at the 2004 Summer Olympics, Montgomery finished in 35th place with a time of 2:15:25.62.
