Edith Chewangel Masai (born 4 April 1967) is a Kenyan former long-distance runner who specialised in cross country and track races, then road races in her late career. She represented Kenya at the 2004 Summer Olympics. Her best achievements are three individual gold medals in the short race at the IAAF World Cross Country Championships between 2002 and 2004.
She is also known for reaching global top at the age of 35. On the track she was the bronze medallist over 5000 metres at the 2003 World Championships in Athletics and was the 2006 African Champion over 10,000 metres. She has also won silver medals over 10,000 m at the 2007 All-Africa Games and 5000 m at the 2002 Commonwealth Games.
Her track best of 8:23.23 minutes for the 3000 metres, set in 2002, remains the African record for the event. Over the marathon distance, she ran her career best of 2:27:06 hours to win the 2005 Hamburg Marathon.
Masai was born in Chepkoya village, Mount Elgon District. She competed during her high school days while at Kibuk Secondary School. She graduated in 1988. She joined Kenya Prisons Service in 1990, known for recruiting many talented athletes. Masai did not, however, achieve anything until 1999, when she became the national cross-country champion, at the age of 32. Consequently, she started training more seriously. She won the Lotto Cross Cup Brussels in 2001 and went on to take bronze in the short race at the World Cross Country Championships that year. She improved upon this the following year, taking the gold at the 2002 IAAF World Cross Country Championships.
She won a bronze medal at the 2003 World Championships. In 2004 she failed at the Kenyan trials for the Olympics, but since she was one of only three Kenyans who had beaten the Olympic "A"-qualifying time in women's 5000 metres that year, she was offered a place on the team. Masai herself initially rejected the offer, but joined the team after lengthy negotiations. At the Olympics she dropped out suffering a hamstring injury. She made her marathon debut at the age of 38, but gave a confident first performance, clocking 2:27:06 to win the 2005 Hamburg Marathon.
She finished fifth at the 10,000 metres race at the 2005 World Championships in Helsinki, Finland. Her time, 30:30.26 was a new Kenyan record. The record was beaten by Linet Masai at the 2008 Olympics, who run 30:26.50.
Masai has since been shifting from track running to marathon. She won Hamburg Marathon in 2005 and participated it also in 2006 and 2007. In 2006 she won Berlin Half Marathon, setting the fastest half marathon run that year, 1:07:16 minutes. It was also a personal best and a course record. She also set a new 5000 metres Kenyan record of 14:33.84 minutes.
She won 10,000 metres silver medal at the 2007 All-Africa Games. Her time, 31:31.18 is a new World record for Over 40 year old women. The previous record was held by Nicole Lévêque of France, who run 32:12.07 in Helsinki in 1994. Masai participated the 2008 World championships marathon in Osaka, Japan, finishing 8th in a race won by her compatriot Catherine Ndereba.
