Kenya’s Abraham Kiptum, the world record holder in the half-marathon, was ruled out of the London Marathon on Friday after being provisionally suspended over irregularities in his biological passport, the Athletics Integrity Unit (AIU) announced.
“The AIU confirms a provisional suspension against Kenyan long-distance runner Abraham Kiptum for an Athlete Biological Passport violation under the International Association of Athletics Federations (IAAF) anti-doping rules,” tweeted the AIU.
According to organisers Kiptum left the city following the suspension issued by the Athlete Integrity Unit.
Kiptum, 29, set a new world half-marathon record in Valencia in October 2018 , running a time of 58 minutes and 18 seconds.
He has a personal best time in the marathon of 2 hours, five minutes and 26 seconds, achieved when he won in Amsterdam in 2017.
Hugh Brasher, Event Director for the Virgin Money London Marathon, said:
“We have a zero-tolerance policy on doping. London is part of the Abbott World Marathon Majors and we recently announced a groundbreaking extensive intelligence-driven testing programme. This shows the programme is working. Cheats will be caught and there is no place for them in marathon running.”
The build up to the 2019 London Marathon has not been without drama.
There was also a dispute between distance running greats Mo Farah and Haile Gebrselassie, following an altercation surrounding an alleged theft at Gebrselassie’s hotel in Ethiopia.
How biological passports work
An athlete biological passport is an individual electronic record for professional athletes, in which profiles of biological markers of doping and results of doping tests are collated over a period of time. It monitors selected variables (`biomarkers of doping´) over time that indirectly reveal the effect of doping, as opposed to the traditional direct detection of doping by analytical doping controls.
