I have never understood why it is such suicide to lead a race early. I am not an elite, but any race that I can do so, I will lead from the gun. I am not Johnny Gray, but the confidence he has when leading seems similar to what I feel.
The worst example of this 'taking the lead' excuse was when Steve Scott led for only 400m in the 1984 Olympic Final (I was actually in the stands for it). He ran about a 57.5 sec. lap, which was well within himself as he was in his peak years at that time. But heavens forbid, no one was in front of him, so the lactic acid kicked in sooner!!
I realize that when a pace is faster than what is normal for you, then sitting behind can pull you along. I also realize the drafting concept during windy days....and I realize again that for some people, the sit/kick strategy may be confortable. But normally, holding competition back during the last 400m is a lot easier than trying to go by 3-4 people in order to win. If a runner doesn't want to lead from the gun, I would think taking control at about 800m would be a great strategy.
Don't misunderstand my comments.....I am criticizing this time! Maybe someone can explain the 'don't lead at any cost' concept, so I can understand.
