Boldon won his first international senior-level medal at the 1995 World Championships, taking home the bronze in the 100 m. At the time, he was the youngest athlete ever at 21 years of age to win a medal in that event. The following year at the 1996 Summer Olympics, he again placed third in the 100 m and 200 m events, both behind world records. In 1997, he won the 200 m at the World Championships in Athens, Greece; his country's first world title in the Athletics World Championships. This made him one of only a few male sprinters to win both a World Junior and World Senior title.
