event. She also beat Kenyan 800 m women's record twice. Jepkosgei was awarded the 2006 Kenyan Sportswoman of the Year award. Jepkosgei made Kenyan History on 28 August 2007, where she won gold in the World Championship 800 m final in Osaka, becoming the first female Kenyan middle distance runner to achieve gold over 800 m. She led from start to finish to win in a time of 1 minute, 56.04 seconds, beating the Kenyan record and world leading time (1.56,18) she had set at the heats two days earlier. She retained the Kenyan Sportswoman of the Year award. On 24 May 2008 the 19-year-old Pamela Jelimo set a new Kenyan record of 1:55.76, beating the one previously held by Jepkosgei. Jelimo's dominance throughout the season prevented Jepkosgei from major victories, but won Olympic silver medal over 800 m. She collided with Caster Semenya of South Africa such that Jepkosgei fell and finished last in her heat at the 2009 World Championships. However, after a successful protest, she was allowed to run in the semi-finals and eventually achieved silver medal, well behind the winner Semenya. Jepkosgei started her 2010 season by a win at the Diamond League meeting in Shanghai, China. Her father Michael Busienei was an 800 m runner, as is her younger brother Dennis Kiprotich. Jepkosgei is now coached by Claudio Berardelli. Her manager is Federico Rosa.
