The 2020 World Half Marathon Championships are going to be incredible but they will not include three-time defending champ Geoffrey Kamworor. Kamworor fractured a tibia in a car accident in June and his agent has told LetsRun.com that the World Half is "not in his plans." But 7:26/12:48 man Jacob Kiplimo has been added to the field and it also might include Norwegian superstar Jakob Ingebrigtsen.
