Abraham Kiptum

Abraham Kiptum is a Kenyan long-distance runner and former half marathon world record holder. On 28 October 2018 Kiptum ran the Valencia Half Marathon in Valencia, Spain in a time of 58:18, which would have been a world record (world record 58:23), but in 2019 this world record was nullified, because of a doping violation verdict in 2019. The half marathon world record was then improved by Geoffrey Kipsang Kamworor on 15 September 2019, to a time of 58:01.

Kiptum's debut in the marathon was the Rabat Marathon in 2015, where he placed third with a time of 2:11:36. In the inaugural Abu Dhabi Marathon on 7 December 2018, he finished as the runner-up with 2:04:16, 12 seconds behind the winner Marius Kipserem. He improved his PB from the 2017 Amsterdam Marathon by 70 seconds.

On 26 April 2019 The Athletics Integrity Unit confirmed a Provisional Suspension against Kiptum for an Athlete Biological Passport (ABP) violation under the IAAF Anti-Doping Rules. Kiptum was withdrawn from the 2019 London Marathon in consequence of the suspension. On 11 November that year, a four-year suspension, and expunging of results, was confirmed. Kiptum's race times going back to 13 October 2018 were nullified.
