Sentayehu Ejigu Tamerat (born 21 June 1985 in Debre Markos, Amhara Region)[1] is an Ethiopian long-distance runner, who specializes in the 3000 and 5000 metres.

She began entering competitions and her immediate success led to a move to Addis Ababa to train with the Banks Running Club.

She soon changed her focus to longer distances and competed on the 2002 IAAF Golden League circuit, recording a 3000 metres best of 8:48.30 minutes at the Weltklasse Zurich at the age of seventeen.

[1] Despite her athletic breakthrough, that year also took its toll on her body as she acquired a long-term problem in her heel and calf which affected her running.

She married Berhanu Alemu, a fellow runner, and began to come back to full-time professional competition in 2009.

[14] A road debut over 10 km followed later that month and she pipped Dire Tune at the line to take the World's Best 10K in Puerto Rico.

[17] She made her half marathon debut in Delhi that December, but her time of 1:12:02 hours left her out of the top ten in the high calibre race.
