I see Hall, Meb, Abdi, Culpepper and a few others breaking away around 15 miles and sorting things out after that.
Culpepper likes to hang back and come from behind. I'd be surprised if he breaks away that early with a lead pack. If they just run conservatively and people drop off the lead pack, then AC will be there. But if there are any major accelerations, I think AC let's them go and tries to pick them off late.
Assuming everyone has a good day, I don't see anyone hanging with Hall.
