Moses Cheruiyot Mosop (born July 7, 1985 in Kamasia, Marakwet District) is a Kenyan middle and long distance athlete. He competed for Kenya at the 2004 Olympic Games and went on to take 10,000 metres bronze at the 2005 World Championships in Athletics. He has also been successful in cross country running, having won the silver at the 2007 IAAF World Cross Country Championships as well as team gold with Kenya in 2007 and 2009.
He is managed by Jos Hermens and coached by Renato Canova. At the 18 April 2011 Boston Marathon, Mosop and countryman Geoffrey Mutai ran the fastest times ever recorded for a marathon - 2:03:06 and 2:03:02, respectively - shattering the Boston course record by nearly three minutes.
 Early running
He started running while at primary school and later went to Marakwet High School. He qualified for the 2002 IAAF World Cross Country Championships held in Belfast, where he finished tenth in the junior race. It was in this occasion that he joined the management of the Italian Gianni Demadonna, and started to be coached by Renato Canova, that developed his talent from the youth category up to the current international level.
At the 2002 IAAF World Cross Country Championships in Lausanne he fared slightly better, finishing 7th in the junior race. At the 2003 All-Africa Games, he was fifth in men's 10,000 metres. He made his Olympic debut at the 2004 Athens Olympics and was seventh overall in the 10,000 metres final. Mosop also won the Giro Podistico di Pettinengo 9.6km race in 2004.
He was the winner of the Almond Blossom Cross Country in March 2005 and placed 18th at the 2005 IAAF World Cross Country Championships soon after. Competing in the 10,000 metres in the 2005 World Championships, he won the bronze medal, setting a personal best of 27:08.96 minutes. He occasionally runs the 3000 and 5000 metres and holds personal bests of 7:36 min and 12:54 min in those events.
He headed further up the podium at the 2007 IAAF World Cross Country Championships. He finished second in the senior race and took the team gold with Kenya. He took back-to-back wins at the Giro al Sas 10K race in 2007 and 2008. In March 2009 he won the Cross di Alà dei Sardi in Sardinia. He returned to world competition two years later, but he could not repeat his medal form at the 2009 World Cross Country Championships (finishing in eleventh place), although he still won team gold with Kenya.
Mosop won the men's race at the 2010 Stramilano Half Marathon, clocking 59:20 for the win over Silas Kipruto. His coach stated that Mosop was progressing as a road runner and might make a move to the marathon distance. Attempting to defend his title at the Giro Media Blenio 10K (which he won in 2009), he finished second in a sprint finish just behind Imane Merga. He was chosen for the Kenyan team at the 2010 IAAF World Half Marathon Championships and he finished in tenth place. At the Zevenheuvelenloop 15K race, he was off the pace and finished sixth – almost two minutes behind Leonard Patrick Komon who set a world record.
 2011: Marathon debut and world records
His first race of 2011 was the Paris Half Marathon, where he finished second behind Stephen Kibet. On April 18, 2011, he ran 2:03:06 at the Boston Marathon, coming second. He and fellow countryman Geoffrey Mutai ran the fastest times ever recorded for a marathon, shattering the time of the then existing world record (2:03:59 by Haile Gebrselassie) by nearly one minute, and the Boston course record by nearly three minutes. Helped by ideal cool temperatures and a strong tailwind on the point-to-point course, the lead pack reached the halfway mark on record pace of 1:01:54. The two Kenyans broke away from the pack at 30 kilometers and ran stride-for-stride over the last 12 kilometers (seven miles) until a sprint in the final straight-away by Mutai gave him the victory by four seconds, 2:03:02 to 2:03:06.
It was Mosop's first marathon race, but because Boston is a point-to-point course, with an overall downhill slope, the times were not officially recognized. The IAAF rules require marathon records to be established on a loop course (thereby neutralizing the impact of wind and course elevation changes.) The previous record at Boston was 2:05:52, set in 2010 by Robert Kiprono Cheruiyot who was the first to break 2:06 at Boston, while the officially recognized world record is 2:03:38, run by Patrick Makau at Berlin in 2011.
As part of the 2011 Prefontaine Classic, Mosop was selected in an attempt to break the world record for the infrequently contested 30,000 m on the track. He shattered Toshihiko Seko's thirty-year-old world record by over two and a half minutes, running a time of 1:26:47.4 hours. He also smashed Seko's 25,000 m record by a minute and a half, passing the 25K intermediate mark at 1:12:25.4 hours. He stepped down in distance to run at the B.A.A. 10K in June and took third place on the podium.
On October 9, Mosop won the Chicago Marathon with a time of 2:05:37, beating Sammy Wanjiru's course record by four seconds. At the start of 2012, he was sixth at the Paris Half Marathon in preparation for the Rotterdam Marathon the following month. He was the pre-race favourite and attempted to break the marathon world record, but fell behind Yemane Tsegay and Getu Feleke, eventually finishing with a time of 2:05:03 hours. Nevertheless, he was selected for the Kenyan Olympic marathon team, but a tendon injury forced him to withdraw and he was replaced Emmanuel Mutai.
 Personal life
In 2005 Mosop was reported to be married with Rose Cheruiyot (not the runner of the same name) with one daughter.  As of 2010, he is married to the runner Florence Kiplagat, with whom he has also a daughter, named Aisha. His brothers Elias Mosop and Philemon Mosop are also runners.
