Ok i need help as I had a run that freaked me out a bit.
I ran my usual "long" run for the week today as usual with a target of 8 miles. It wasn't TOO hot being only 80°F, although humidity was high. For some reason, after mile 4, I hit a huge wall. I can't even put my finger on it. My legs were fatigued but still going strong, my breathing and heart-rate was stable, albeit a bit high at 170+ for the moderate pace I was running at, but I just felt weak. Almost as if someone sucked the energy out of me. It was the strangest thing and for the first time ever I had to walk occasionally to take breaks. Such a bummer
The only thing I can think of is that I, for some reason, took my
preworkout before running. I usually only take this on lifting days. I didn't think it would have a negative impact on endurance, but maybe I'm wrong?
