He didn't finish well, that's true. But having run more than 70 marathons myself, I have found that just about everybody drops off towards the end. It's usually the guy who drops off the least who wins. Unless that guy is Wilson Kipsang, I guess. What a phenomenal runner.
Anyway, I went back to the London results, and while Mo didn't exactly pick it up at the end, he wasn't exactly puking on the sidewalk either. To compare his 5k splits with Ayele Abshero, who finished a respectable 4th, in 2:06:31
Ab: 14:21 14:51 14:55 15:09 3:15 11:29 15:02 15:01 15:34 6:54
Mo: 14:48 15:08 14:54 15:05 3:13 11:39 15:18 15:36 15:52 6:48
I didn't watch the race, but from what I read, at some point around 10k Mo decided that the group he was running with was moving too slowly. And from the splits, it would appear at 10k he was 36 seconds behind and losing ground. So he tried to go after the leaders, but could find nobody to go with him. And for about 10k he was running alone, which can really take it out of you, physically and psychologically. The splits suggest that around the halfway mark, this effort caught up with him a bit, particularly in that awful stretch between 35 and 40k (which as I remember, is a nice flat run along the Thames leading to Parliament, and not particularly taxing). Still, he does seem to have pulled it together a bit for the last 2.2 km, in fact running it faster than Abshero.
This is what I meant by poor tactics. Of course it is possible that had he gone out with the lead group he would have really hit the wall. Geoffrey Mutai did, and he is certainly a proven world-class runner who came into London in terrific shape. But had Mo gone out with them, he would have had the advantage of being able to run a steady pace, rather than play catchup for 10+ km, not to mention being able to hide from whatever wind was present, and to turn it off a bit mentally and just relax and follow the group. Instead his strategy was ragged, and in that situation, 2:08 isn't bad at all. I mean, he ended up nearly catching most of that lead group in the end. Even though at least one of them (Emmanuel Mutai) admitted to picking it up in the stretch to avoid being beaten by Mo, still he was only 2 secs behind Emmanuel Mutai, and 3 behind Geoffrey Mutai; hell, he was only 15 secs out of a 5th place finish. IMO not terrible, certainly not on your first attempt.
I would also argue that Mo didn't do himself any favors by running the NYC half only 4 weeks out from London. I'm nowhere near the class of these guys, not to mention much older, and take much longer to recover. But my experience is that we underestimate how much a hard run half marathon takes out of you. For me, it's two weeks before I'm back to where I was before the run. It's not just the run itself, it's the disruption to the schedule of tapering a bit for the half, recovering, not to mention the traveling before and after the race, days when you can't always get good training sessions in. And in Mo's case, there was the additional baggage of falling at 6 km, then running himself into the ground trying to catch up, to the point where he fainted after crossing the finish line. I doubt the actual fall hurt him much, although it may have, and may have at least added to the loss of good training. But I would bet that running 1:01:07 even after the fall really took it out of him. And I would bet that even if the fainting episode really was no big deal physically, it weighed on his mind a bit in London, when he found himself really starting to hurt.
To be honest, I suspect NYC half winner Geoffrey Mutai would pass on that race if he had it to do over again. It seems to have taken a bit out of him for London, too. He's running the 10k in my home town this weekend, and is doing an autograph signing session tomorrow. I'm kinda intrigued by this question, since running halfs to test fitness before a full seems to be becoming a standard practice, so I'm going to do my best to ask him his thoughts.
In my opinion, Meb did the right thing in the NYC half, running it hard but not at maximum pace, finishing in 1:02:53. You don't want to leave your best race in the training bin. Plus his marathon was 5 weeks out, in Boston. Now there's a guy who seems to be able to get himself to the big race fit and healthy. Well, barring having to hurdle dogs, which as I remember caused the injury that hobbled his NYC marathon last fall. I hope he turns to coaching when he finally quits running. I suspect he'd be exceptional one.
Anyhow, I know Mo is an easy target for those who mistake sarcasm for humor. He didn't run a great initial marathon, and to make things worse, Bekele did. It can take some time to learn the marathon, and under the circumstances, I don't think Mo ran a terrible debut.
So I hope he sticks with it. Additionally, if he does decide to go back to the 5 and 10 km, I would be worried that Bekele would follow him. And frankly, if Bekele can get anywhere near the shape he was when he set those world records, Mo will have a heck of a time winning any more medals. Will Bekele drop down? He didn't sound very committal after beating Wilson Kipsang in that 10k recently, and I read on Letsrun that he found a lot of the training for Paris 'boring'. Maybe he still considers the 5 and 10 k 'his' races.
