Sometimes, about a minute or two into my run and usually when I haven't warmed up adequately, I get this awful sensation like something is washing right through me. I don't know what it is, a rush of chemicals or hormones or something, but it's extremely unpleasant and I absolutely detest it. It is this sensation that prevented me from becoming a "real" runner for a very long time because when it comes over me it makes me feel so weak that the effort of continuing to move forward seems impossible. It used to stop me cold but now I push through it and it's over and forgotten in a minute. It hasn't happened for a long while so I had forgotten about it but it happened twice this week. I didn't warm up for either run, just headed straight out, so I guess that's the cause. Anyone know what it is? I hate it. Hateithateithateit.
And another thing! During my last two runs I have gotten into a groove where I feel like I'm on auto-pilot. My legs don't even seem to belong to me. I'm a machine from the hips down and the run is all in my head. What is up with that?
