In a well-rabbitted raced, I think Rupp could go 3:48
Really, unless we know the planned rabbit pacing, or strategies, the best we can guess is what the ceiling might be. I guess people could take the average of all past miles here and do some statistical modeling, but I would say his ceiling is 3:48, but wouldn't be that surprised if his ceiling was approaching 3:46 territory. Call me crazy. He ran 3:50 indoors solo. That was what, 6 months ago?
Although, he's probably been doing more threshold training, because I think they plan their workout regiments in blocks, where after the US Champs, they rest and start a second cycle of rebuilding on top of the previous, err something like that. I bet he cold easily beat Brannen in a 2000m right now. I'll say that much....
... and Rupp takes 3rd
