It is the International Athletics Federation, IAAF, Integrity Unit, AIU, that shut down the 30-year-old Kenyan for four years because of discoveries that prove Epo-doping in his biological passports, writes Athletics Weekly.

AIU temporarily shut down Kiptum in April and now deletes all results from October 13, 2018.

This means that his time of 58.13 on the Valencia half march October 28, 2018 is now expired. It was then world record in the distance. That time was undercut by compatriot Geoffrey Kamworor (58.01) in Copenhagen in September.

According to the documentation in the case, Kiptum disputes the information that he must have doped or used methods that can explain the positive result. Kiptum's own explanation is that he has trained at high altitude.

Kiptum can appeal the decision.
