I can only assume it's talking about Patrick Makau, who ran the 2011 Berlin Marathon in 2:03:38. Taking seconds off of that time would be more impressive than hours off of this fat asses.  Let's see. 42.195 km in 218 s is 193.555 m/s. So he could run 100 m in 0.517 s. Or 18.543 times as fast as Bolt's 100 m world record. That would be impressive. But the above doesn't figure in acceleration so the numbers are a bit unrealistic.
