Aadam Ismaeel Khamis

Aadam Ismaeel Khamis (آدم خميس إسماعيل) is a long-distance runner now representing Bahrain after his switch from Kenya.

According to Bahraini officials, he was born Hosea Kosgei on 12 February 1989 in Kenya. Like fellow Bahraini runners Belal Mansoor Ali and Tareq Mubarak Taher, his age is surrounded by controversy. In August 2005 the IAAF opened an investigation on their ages which was still ongoing.

In 2006 Khamis won a bronze medal over 3000 metres at the Asian Indoor Athletics Championships. At the World Junior Championships in Beijing the same year he won a bronze in 10,000 metres and finished fifth in 5000 metres. The IAAF Council opened an investigatory disciplinary file on Khamis the day after his 5000 m finish.
