Note: In its London preview, American fan website letsrun.com inexplicably calls Ozaki, the 2009 World Championships silver medalist, a 'wanna-be.' It also incorrectly claims that she has never won a major marathon despite then listing her 2:23:30 win, which came at the 2008 Tokyo International Women's Marathon, one of the world's premier elite women's races, rather than the 2008 Tokyo Marathon as suggested in the website's preview. In her Tokyo International Women's Marathon win Ozaki beat London entrants Mara Yamauchi (GBR) and Svetlana Zakharova (RUS), 2009 Boston Marathon winner Salina Kosgei (Kenya), 2009 New York City Marathon winner Derartu Tulu (Ethiopia), 2:19 woman / 2009 Osaka International Women's Marathon winner Yoko Shibui (Team Mistui Sumitomo Kaijo) and 2009 World Championships team member / 2010 Nagoya International Women's Marathon winner Yuri Kano (Second Wind AC).
Besides these two strong performances, Ozaki was 2nd in her debut marathon at the 2008 Nagoya International Women's Marathon, a close 2nd behind London as the world's top-ranked elite women's marathon. London will be Ozaki's 4th marathon. As she states in the article linked at the top, her goal is a 2:21.
