I will go out on a limb and says he runs a sub 2:08, and here are my reasons. I will say he went into this race with very little to no taper. Compound that with a cross country flight and it's no surprise he was tired in the last 11K of the race. When Chicago rolls around he will be rested and won't have to travel as far plus he will arrive at the race several days earlier than I'm sure he did for Philly. It would no surprise me to see him run back to back 63:55 1/2's which is what he ran for his half today.
