El Mahjoub Dazza has 2:05:26 PB and few days ago he was suspended for ABP.
Yes, and half marathon world record holder Kiptum was doped when he ran his 2:04:16.
Moreover, ex world record holder and multiple 2:03 runner Kipsang just got (provisionally for now) banned for his anti-doping-rule-violations.
It's even worse among the ladies:
The current world record holder (women's only) got her passport flagged as suspicious in 2016, and then ran that world record in spring 2017.
Liliya was doped when she became the third fastest woman ever. At that time, the then world record holder stood already out (unbeknownst to the public) with her two absurdly high off-score jumps within a few days in 2003 and 2005, with the world record from 2003.
Last but not least, the last Olympic Champion was banned for doping, as was the silver medalist, further cementing how dirty the sport is and how successful its dopers are.
And this is just for the marathon, to stay on topic.
