Brimin Kipruto (born 31 July 1985) is a Kenyan middle distance runner who specialises in the 3000 metres steeplechase. He was born in Korkitony, Keiyo District. He holds a personal best of 7:53.64 minutes which is the second fastest time ever run, and the African Record.
He won a silver medal at the 2004 Summer Olympics at the age of nineteen and improved to win the gold medal at the 2008 Beijing Olympics four years later. A World Championships bronze medallist in 2005, he took his first global title in the steeplechase with a win at the 2007 World Championships in Athletics
At the 2001 World Youth Championships in Athletics in Debrecen, Hungary he finished second in steeplechase. He graduated from Kipsoen Secondary School in 2003. The same year he competed at the African Junior Championships in Cameroon and took silver again. At the 2004 World Junior Championships in Athletics he competed in 1500 instead of steeplechase and finished third.
In 2004, having finished 2nd at the Kenyan Olympic trials, the young Kipruto won the silver medal in the 3000 m steeplechase at the 2004 Olympic Games. In the 2005 World Championships in Helsinki he won a bronze medal in the same event. He finished third again at the 2005 IAAF World Athletics Final. In 2006 he finished sixth at the World Athletics Final, repeating his place from 2004.
In 2007, he won the gold medal in the steeplechase at the World Championships, in Osaka. After qualifying to the 2008 Beijing Olympics, Kipruto finally won the gold medal at the same event. At the 2009 World Championships, the defending champion finished only seventh.
He took two wins on the 2010 IAAF Diamond League circuit, finishing in first place at the Athletissima and Meeting Areva, but it was Kenyan rival Paul Kipsiele Koech who went on to win the inaugural Diamond League trophy in the steeplechase. He entered the 2010 Commonwealth Games with the fastest mark of the year (8:00.90), but could only manage third place behind Richard Mateelong and Ezekiel Kemboi as part of a Kenyan medal sweep.
