Mo Farah, the greatest track distance runner of the last decade, notched his first marathon win, taking the Chicago Marathon on Sunday.
Farah, a four-time Olympic champion between the 5000m and 10,000m, clocked an unofficial 2:05:11, which would break the European record of 2:05:48.
Farah won by 13 seconds, kicking away from Ethiopian Mosinet Geremew in the last mile.
Pre-race favorites American Galen Rupp (2:06:21) and Geoffrey Kirui of Kenya (2:06:45) were fifth and sixth.
Rupp, who formerly trained with Farah, dropped from the leaders around mile 19.
