As a side point, I don't think humans were designed at all, let alone for some narrow purpose to run fast. Do you also think we were designed to throw far, and jump high too, and it's simply a lack of the right training? Compared to many other animals, humans run quite slow. Dr. Lieberman makes some good arguments that we evolved to run long, not fast.I'm just saying you are talking about two different things. Surely everyone has room for improvement, but for most people "running much faster" is not the same as setting "world records". Personal bests and world records are not the same thing, except for a select few people. Western nations produce 1 elite athlete per 20 million persons. I somehow doubt this is because 19,999,999 have yet to discover two-footed jumping, but maybe I'm naive.All this talk about working on strides, can only lead to personal best performances, for 19,999,999 out of every 20,000,000 people.The ones who will set world records will also train hard, plus have an inherent advantage predetermined by their genetic makeup. Faster world records will likely produce longer strides, and quicker stride rates, as you suggest, but that will come from both a higher inherent potential, combined with the right training.

So you think that we don't already have the genes to run much faster? You think that such performances requre that the runner/runners would be genetic freaks?
That is a very naive argument, it implies that we humans aren't designed to run fast.
