"Hall, who is signed up for this April’s Boston Marathon, took a philosophical approach to his rare loss.
"'The goal was to go out fast and practice for the pace I’ll need to run later this season,' said Hall, who passed the 2 mile mark in 9 minuets flat, sub 59:00 half marathon pace. 'Boston is the big picture, so this was a test to see where I am and I still have New Orleans to go before Boston.'"

Although I may be wrong, by the way Hall mentions New Orleans it sounds like he was (more than a?) little disappointed in this effort and will be looking to run (substantially?) faster in six weeks.
I agree with some folks who believe Hall needs to focus on the half/10k for a while and get a different stimulus.
Great run by Bairu.
