Komu started her education at Nyakiambi and Lariak primary schools. In 1997 she went to Laikipia High School, where she started running. In her early career she took part in various road running and cross country running competitions, but without major success. In 2003, she moved her base to France, where she represents the Clermont Athlétisme Auvergne athletics club.[1]
After a maternity break in 2005, she returned to competition in 2006 and won the Mont Saint-Michel marathon, her debut marathon. She also won the Rheims marathon in 2006 and 2007. In 2008, she won the Paris Marathon, setting a personal record of 2:25.33 hours. This performance earned her a place in the Kenyan Olympics team. Her husband Simon Munyutu finished 11th in the men's race at the 2008 Paris Marathon; their combined time of 4:34:57 hours, according to marathon statistician Marty Post, is the best achieved by a married couple in the same marathon.[1]
