Career Highlights: An Olympic gold medal - something Rudisha will likely be heavily favored to win in the 800 meters in London - would cap an already dazzling list of accomplishments for the 23-year-old Kenyan. "Being the world record holder and world champion, those are good titles, but I am missing the big one, the Olympics," Rudisha said earlier this year, adding what almost sounds like a guarantee: "I'm not going there to lose. I'm going to win that title." It would be difficult to doubt him after he broke the 13-year-old world record in the 800 in 2010, then bested his own mark with a time of 1:41.01 a week later. Those performances earned him the IAAF's World Athlete of the Year award, making him the only man besides Usain Bolt to win it in the last four years. Rudisha followed his record-breaking season with a gold medal at the 2011 world championships, beating rival Abubaker Kaki by half a second in the final as part of a 34-race winning streak in the 800. Among his other gold medals at that distance are two from the African championships (2008, 2010) and one from the 2006 world junior championships. Rudisha also hopes to run in the 4x400-meter relay in London after his father, Daniel Rudisha, helped Kenya win a silver medal in that event in 1968.
