Career
Early life
Masai was born in Chepkoya village, Mount Elgon District. She is the third born from a family of four. 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.[2] 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 after suffering a hamstring injury.[4] 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.[5]
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.[8]
She currently lives in Ngong and Kitale. She coaches the Kenya Prisons Cross Country team. She is a divorced mother of one, her son Paul Griffin Sakit born in 1992 who ran for Louisiana Tech University. Masai retired from competitive running in early 2010 because of a knee injury.
