Meb has already mentioned that he'll be running a Fall Marathon, but hasn't named it yet. While he normally runs NYC, it's a very real possibility that he'll choose Chicago as he already won Boston and NYC, and he would love to add the final US Major to his list of titles.
Knowing that he would have a very slim chance of winning in a rabbitted race, did the Chicago organizers end the rabbit tradition to ensure a Meb appearance?
