This is just so sad. I watched the video of FM as the barefoot running doctor. He's trying to make a difference in fighting obesity and diabetes. I strongly support those issues. I can't wrap my head around why someone like this would cheat.
It obviously required a lot of meticulous planning. On page 39 of this thread, I described how it could be done.
The following sequence of events would be enough to convince a jury.
At the LA Marathon, FM comes through the 15k mat 17 seconds behind Greek Guy and Woman in Black by clock time.
A photographer was taking photos between the 15k and 20k mats. The runners were spread out at this point and photos were taken with a telephoto lens, which gives the photographer plenty of time to get each runner, but FM never shows up in this sequence of photos, either before or after the Greek Guy and the Woman in Black.
At about the 11.5-mile mark, a sequence of photos shows someone (FM?) apparently entering the course just behind Greek Guy and Woman in Black. This is FM. If he had been running nonstop since the 15k mat, he would have had to run roughly 6:20 to make up that 17-second gap to Greek Guy and Woman in Black.
Yet over the next few photos of Greek Guy and Woman in Black, FM gets outrun by several meters in less than 100 yards! There is no plausible explanation for why a runner would close a 17-second gap in two miles and then lose 10 meters to those same runners in 100 yards. The logical explanation is that for some logistical reason, he had to reenter the course sooner than at other times, so he couldn’t maintain their pace for the 0.9 miles to the 20k mat.
By the 20k mat, FM has lost 1:40 to Greek/Woman in Black. That would have been roughly an 8:10 pace over 0.9 miles.
