I agree with Costly.
God bless them for trying, but just because Alberto does it doesn't make it right. He may have run even faster and got that world record. Yes, I can't prove that but others can't discount it.
My point: How much fitness did he gain from the post 5000 workout that would have helped him in the 2 mile effort just days later? The answer none. So if you're going for the 2 mile record, why not be rested after such a tough race? Going for some psychological advantage is plain silly.
I can't wait for the "pros" to rip this apart. Me, I'm just a 2:31 marathoner (Boston), so I must know nothing, right?
