determined said:Almost invariably, the first mile I run just kills me. I start out
feeling stiff, distracted, etc.
It's at least very common if not universal for the first part of a run
to be less pleasant. The concept of warming up didn't come from
nowhere, and if you aren't completely warmed up before a run, you'll
have to do so during it.
If the first mile is "killing" you and not just moderately stiff and
awkward, you might want to try it slower.
I find that doing other things to warm up a little - some self massage
with "The Stick", some Whartonesque dynamic stretching, etc - seems to
help somewhat, as in maybe the stiff and awkward phase is less
pronounced and over quicker.
