Most athletes will perform a number
of what are called
strides prior to a running session,
or at least before one where there is to be any running
at a significant speed.
Strides, or run-throughs as
they are sometimes called, are runs over about 60m to
100m, where the speed of the runs should be fast enough
that you are running on your toes, but a long way short
of outright sprinting. Athletes are commonly told by
coaches to try to run at about two-thirds of their top
speed.
