I dont think anyone is a shoe in.
Ritz is he is healthy and has a good day obviously can be up there.
Same thing for Meb, but again he has to have a good day.
Hall is a big ?, I know everyone is counting him out, but if there is anyone that can come back and run a 2:09 it is Hall.
Puskedra had a great day in Chicago and may be able to duplicate that effort.
Kibet has a big up side and seems capable of a sub 2:10.
Llano seems to capable of something around 2;10 as well.
Estrada on paper seems like he should be able to run 2:10 or faster. However as we know there are a number of runners on the world scene that have run a fast half and it never translated to a fast marathon.
I think the pace will be fast from the gun as there are just too many guys who have nothing to loose and will not let it be turned into a 20 mile tempo with a 10k race.
Chelanga is another that has the potential to run very fast, although he is untested at this distance.
It is going to be one heck of a race, hopefully it will be streamed live and be good coverage.
