No post from the OP in 6 weeks. Have you considered that maybe he actually ran a FAT race? It's not necessarily that this was a troll....but distance people tend to have a HIGHLY exaggerated view of their speed.
There's a section in Dr. David Costill's book "Inside Running: Basics of Sports Physiology" where he discusses an athlete that had trained for the US Olympic Marathon Trials. Costill measured the guy's vertical jump at less than a foot. When the guy stopped running all that mileage, his vertical jump roughly doubled. That's what that mileage does for an to people: It makes you slow and weak, but you can go slow and weak for a long time. It does NOT make you fast.
Sprinters reach 90 percent of their max speed by 40 meters (or 5 seconds or less). The IAAF Biomechanics Project measured Bolt's 99% point of the 9.58 at 48 meters. It has often been said that the race starts at 50 meters (who slows down the least wins the 100m), but it's also true that if you can't get fast enough by 5 seconds, it doesn't matter what you do--you're not getting any faster after that point.
If Nick Willis can't run a 50 second 400 from standing because he can't get up to speed fast enough, and Farah and Rupp can't run a sub-12 100m (and these people have medals), how is an Average Joe distance runner going to do it?
You have to get rid of the mileage to have a chance, and even then the buildup in acceleration power takes a lot longer than a few weeks
