Robert Kipkoech Cheruiyot (born September 26, 1978 in Kapsabet, Kenya) is the current record holder and four-time winner of the Boston Marathon.
Robert Kipkoech won the Boston Marathon in 2003, in 2006, 2007 and again in 2008. His 2006 Boston finishing time of 2:07:14 broke a Boston marathon course record set by Cosmas Ndeti that had lasted 12 years.
He finished 4th in the 2005 New York Marathon. He sought to win another title in Boston in 2005 as well but only finished 5th that year.
During his win at Chicago in 2006, Cheruiyot did not actually break the tape at the finish line. He slipped at the end and crossed the finish line as he slipped forward making him the winner. It was ruled that he did cross the finish line in doing so. He injured his head against the ground in the fall and had to be helped from the course in a wheelchair. He suffered a brain contusion and was released from the hospital after two days of observation. His time of 2:07:35 was five seconds faster than 2nd place finisher Daniel Njenga. The win in Chicago leaves him at the top of the 2006 World marathon standings and poised to win its grand prize.
In 2007 Cheruiyot defended his title and won his third Boston Marathon with an official time of 2:14:13. Fellow Kenyans were second and third. It was the 15th time in the last 17 years that a Kenyan has won the Boston marathon but it was also the slowest Boston Marathon since 1977 as runners faced cold headwinds gusting up to 50 miles per hour. Cheruiyot also won US$ 100,000 for the victory. With four victories in the World Marathon Majors series, his lead in that series is significant.
His personal best is currently his 2006 Boston Marathon performance.
On April 21 2008, he won his fourth Boston Marathon title with a time
of 2:07:43, making him the first four-time winner in the men's open
division since Bill Rodgers (fellow Kenyan Catherine Ndereba recorded her fourth win in 2005). (source wikipedia)
