Something strange happened while running last night
I have been working myself though c25k actually surpassing it a couple of weeks back, and have been adding a few minutes to my runs since. I'm up to about 40 minutes straight at 5.5mph (yes, on the dreadmill), but I haven't ever felt what I did last night.
It wasn't the "runner's high" because I've experienced that before. Instead, right around the 30 - 35 minute mark, it felt like I was just walking instead of jogging. It felt as though someone literally reached across to my machine, and turned the speed down to my normal walking/cooldown speed. I usually don't check the time/speed while I'm going, but the feeling was so strong, I had to look down to make sure that I was still going at the proper pace.
That feeling subsided after a few minutes, but it was really strange that for those few minutes, I felt like I was performing the most menial physical task.
Does this happen the more your body gets used to a certain pace? I know your heart rate slows down, or at least is harder to get up to a higher BPM with the same level of physical strain. I'm used to that, and have been keeping very close track of it, but I never expected to actually physically feel as though I was not exerting myself whatsoever, especially 30 minutes into it.
Am I going insane, or is this normal when your body gets more used to an activity?
