That's the point, I suppose. The 3000m record is usually out of reach of very fit 5000m and 10000m athletes who don't have the requisite speed, and is also out of range for excellent 1500m runners who don't have the long distance ability. Similar analyses can be made for the 5000m record. Mo Farah is not lacking in either respect, and while I agree that his existing marks don't suggest that he'd be in contention for these records, I don't think he's really gotten a good shot at either yet. Here's to hoping he's able to hop in a fast race and his fitness can truly be tested. Of course, there are no guarantees and I'm merely excited at the prospect of what Farah can do at the intermediate distances with this kind of range.
I'm not so sure that Kiprop has no chance at the 3000m record either. I certainly wouldn't bet on him, though frankly, I wouldn't bet on anyone, as that record is near untouchable. Nevertheless, Kiprop has outstanding 1500m speed and is a former world cross junior champ. He may have sacrificed some endurance under whatever training has enabled him to run 3:27, but I wouldn't so quickly dismiss him. However, I don't think he's interested in the 3000m at the moment, so it's kind of a moot point.
