Geoffrey Kamworor


  • Country: Kenya
  • Date of Birth: 22 November 1992

Geoffrey Kamworor is an all-round athlete born in Keiyo in Kenya. He is being coached by Patrick Sang and trains in the Kaptagat training camp in Kenya. He won his first international medal at the World Cross Country Championships in Punta Umbria (2011) by winning the Junior Race. He soon found out that he wanted to become a marathon athlete, instead of running on the track. This resulted in his first half marathon in 2011. He ran the half marathon of Berlin in a time of 1:00:38. He continued his progress by running a new personal best of 59:26 in 2012. He chose to make his marathon debut in Berlin, where he became third in a time of 2:06:12. Geoffrey ran the fastest half marathon of the year 2013 clocking 58:54 in RAK. Because of this achievement, he got selected for the World Half Marathon Championships in Copenhagen in 2014. There he won his first senior World Championships medal by winning in a time of 59:07.


At the 2015 Kenyans trials for the World Cross Country Championships Geoffrey took the second place but still traveled as the favorite to Guiyang in China. He promised to bring the gold medal back to Kenya and so he did. He won his third golden medal at a World Championship in three appearances. His focus for the remaining part of 2015 was to win the 10.000m gold medal at the World Championships in Beijing. The three Kenyans made it a fast race as this could be a good chance to beat Mo Farah. But Farah showed his top speed in the final lap and Geoffrey had to settle for second, which is a great achievement. He joins Radcliffe and Tergat as the only athletes who have won WC XC, WC Half and WC 10k silver. At the end of 2015 Geoffrey showed again that he is the man of all surfaces, he became second in the New York City Marathon. 

In 2016 Geoffrey became, despite a fall at the start, only the third men in history to win the World Half Marathon Championships more than once. He took the win in a fast 59:10. Another World Championship came up in 2017, the World Cross Country Championships in Kampala. Geoffrey showed the world again that he is the man of all surfaces by winning the gold medal for Kenya.

In the fall of 2017 Geoffrey Kamworor was crowned the winner of the TCS New York City Marathon in a heroic fight with Wilson Kipsang to the finish line. Geoffrey took the victory in a time of 2:10.53.

Geoffrey has been followed by the production company A Cow Says Moo in 2012. They made a documentary about Geoffrey and his road towards his first marathon and is called The Unknown Runner. This became a popular and inspiring app for runners and documentary enthusiasts and gives them an insight into the world behind the Kenyan athletes (
