Hmmm, generally I _do_ vary my stride length to vary my walking speed. The human leg in walking acts
as a pendulum, having a natural period which is mainly a function of its length. In normal walking,
the leg moves at its natural swinginging cadence.
For running or extra-fast walking, one does, indeed force the leg forward faster than its natural
period, but this is not sustainable for nearly as long as walking with a natural leg swing.

Some folks like to do that, and buy cars with manual transmissions even though they can afford
automatics. Not a choice I'd make, but if they enjoy it, where's the harm?
Mostly I ride fixed gear, but when I ride multispeed, I like LOTs of gears, nice and close together.
