to cease what he considered an unprofessional approach to the sport. Bolt began training with Mills in preparation for the upcoming athletics season, partnering with more seasoned sprinters such as Kim Collins and Dwain Chambers. The year began well, and in July, he knocked more than a third of a second off the 200 m CAC Championship record with a run of 20.03 s, then registered his 200 m season's best at London's Crystal Palace, running in 19.99 s. Misfortune awaited Bolt at the next major event, the 2005 World Championships in Helsinki. Bolt felt that both his work ethic and athleticism had much improved since the 2004 Olympics, and he saw the World Championships as a way to live up to expectations, stating, "I really want to make up for what happened in Athens. Hopefully, everything will fall into place". Bolt qualified with runs under 21 s, but he suffered an injury in the final, finishing in last place with a time of 26.27 s. Injuries were preventing him from completing a full professional athletics season, and the eighteen-year-old Bolt still had not proven his mettle in the major world-athletics competitions. However, his appearance made him the youngest ever person to appear in a 200 m world final. Bolt was involved in a car accident in November, and although he suffered only minor facial lacerations, his training schedule was further upset. His manager at the time, Norman Peart, made Bolt's training less intensive, and he had fully recuperated the following week. Bolt had continued to improve his performances, and he reached the world top-5 rankings in 2005 and 2006. Peart and Mills stated their intentions to push Bolt to do longer sprinting distances with the aim of making the 400 m event his primary event by 2007 or 2008. Bolt was less enthusiastic, and demanded that he feel comfortable in his sprinting. He suffered another hamstring injury in March 2006, forcing him to withdraw from the 2006 Commonwealth Games in Melbourne, and he did not return to track events until May. After his recovery, Bolt was given new training exercises to improve flexibility, and the plans to move him up to the 400 m event were put on hold. The 200 m remained Bolt's primary event when he returned to competition; he bested Justin Gatlin's meet record in Ostrava, Czech Republic. Bolt had aspired to run under twenty seconds
