Well, now that we are talking a little bit about these two greats, why the hell is nobody talking about Florence Kiplagat, Rita Jeptoo and the others? The women field is not bad either, even if we are not going to see a WR.
About the men, with a stud like Eliud Kipchoge to go along maybe all the way (and if they don't do anything silly), I would not be surprised if Kenenisa Bekele broke the WR. 2:05:04 in Paris is really good.
It would be a real disappointment if he didn't break the course record.
