to claim a season's best but, despite the fact that bad weather had impaired his run, he was happy to end the meeting with just the victory. However, a sub-20-second finish was soon his, as he set a new personal best of 19.88 s at the 2006 Athletissima Grand Prix in Lausanne, Switzerland, finishing behind Xavier Carter and Tyson Gay to earn a bronze medal. Bolt had focused his athletics aims, stating that 2006 was a year to gain experience. Also, he was more keen on competing over longer distances, setting his sights on running regularly in both 200 m and 400 m events within the next two years. Bolt claimed his first major world medal two months later at the IAAF World Athletics Final in Stuttgart, Germany.

In his debut tournament, he won the gold medal in a time of 10.03 s, feeding his enthusiasm for the event. He built on this achievement at the 2007 World Championships in Osaka, Japan, winning a silver medal. Bolt recorded 19.91 s with a headwind of .
