As a senior, she enjoyed most of her early success in the short race at the World Cross Country Championships. After a lowly senior debut of 78th place in 2000 she steadily improved, taking 18th in 2002, then 11th in 2003. At the 2005 edition her fourth-place finish helped the Kenyan women to the team silver medal. She won the individual silver in the short race at the 2006 World Cross Country Championships, leading the Kenyan team to second place behind Ethiopia. She ran in Italy that year and won both the Cross della Vallagarina and Giro Media Blenio races.
