At 40 years, many long-distance athletes retire to their businesses while others return to their farms where they will enjoy their hard-earned wealth. But not Isaiah Kosgei - a 48-year-old marathoner.
Kosgei started professional running in the mid-1990s before taking part in road races such as See Genezareth Tiberias Marathon in 2005 (in Israel) where he finished third, Karlsruhe Baden Marathon (fourth place) in 2009 and Barcelona Marathon (fifth place) in 2011 among many others.
