Since our daughter was born (she's a little young to be
cycling yet) I've been restricted to no more than about
ten miles a day of my usual form of transport, but have
been obliged from time to time to practice "walking" as
it appears to be called. It's much slower than cycling
as far as I can see, and hurts the legs a lot more over
a comparable distance.
I am happy to report than even after a leg-aching couple
of miles across the Parks, I am still able to leap on
the bike and potter about with no difficulty. Is this
what they mean by "completely different muscles"? If
so, what are all those pedestrians doing with their
cycling muscles? More particularly, why aren't they?
