That's how it felt on the treadmill this morning. I ran the exact same speed/distance/intervals as yesterday (and the day before, for that matter) but for some reason today it was such a struggle. My legs were burning a bit after the first running interval and I didn't think too much of it, but then my precisely timed walk break seemed so unexpectedly short. The second running interval was a definite struggle -- I was fatigued, the air felt thick, I found myself leaning forward while simultaneously landing on my heels more than usual (how does that even work?!), and my calves were burning. The second walk break seemed to last microseconds, and when the third running interval rolled around I found myself thinking "oh no" instead of my usual "let's go"!
My internal pep talk even regressed to monosyllables as I mentally chanted, "Go, go, go. Push, push, push." (Usually my pep self-talks go more along the lines of: "You're strong. You can do this. Just keep moving.") By the time I finished I was panting and wheezing and felt about half dead. It took forever for me to cool down and get my heart rate back to normal.
What gives? I don't know what was different this time. I actually slept better last night than the night before, and had a decent breakfast of protein and complex carbs, but it really was like running through oatmeal today. Maybe it's because it was my third day in a row running the same speed/distance/intervals? Pundits say you shouldn't run every day, but I've found that because of the fibromyalgia, if I don't move every single day my body resets to "zero" and I have to start all over again to build up intensity. It might be time to play around with alternating easy runs vs. hard (for me) runs, though. I definitely don't want to get another injury, and more than that, I want to be having fun!
Yesterday's run was so great, and today it was just torture. Same run, two completely different experiences. Is it the fibromyalgia, or just running in general? Who knows? I just know that for the first time today, with my 5K almost exactly two months away, I started to get a little nervous about it. And that is no place for my head to be while training.
