Edwin Cheruiyot Soi (born 3 March 1986) is a Kenyan professional long-distance runner who specialises in the 3000 and 5000 metres.

His earliest honours were team gold medals with Kenya at the IAAF World Cross Country Championships in 2006 and 2007.

[2] The 2006 season also brought him further success on the road circuit as he won both the Giro Media Blenio and the 10 km du Conseil Général 13 in Marseille, setting a career best time of 27:46 minutes at the latter race.

A fourth place at the trials saw him narrowly miss out on selection, although his track season had a successful culmination with a 3000/5000 m double at the 2007 IAAF World Athletics Final.

In September 2009, he won his second Memorial Peppe Greco in Scicli – an achievement only matched by Haile Gebrselassie and Martin Lel.

[10] He also defended his title at the Giro al Sas 10K race in Trento, seeing off a challenge from Wilson Busienei in the final stages.

[12] He attempted a fourth straight win at the BOclassic, but was beaten into third place by Imane Merga and Mo Farah.

[18][19] In 2013 he focused on 5000 m track running and began his year by ending Mo Farah's year-and-a-half winning streak, beating the Olympic champion at the Prefontaine Classic.

[20] He was only fifth at the Golden Gala but a third place at the Kenyan trials guaranteed his selection for the 2013 World Championships in Athletics.
