It occurred to me on the way to the gym this morning. I did not drink anything when I went to bed and I waited until well after 9 am to have a cup of tea. I did not drink very much yesterday, either, or this whole past week, because when it's cold outside I don't feel like drinking cold water and I was not home enough to make tea. I'll have to remember to bring a thermos from now on. Funny that I also gained two pounds over the last week. I think I ate instead of drinking, an old bad habit that restarts whenever the weather gets cold.
In any case, when I noticed I started drinking about 20 minutes before the beginning of my run and continued drinking throughout the run and finishing about 28 oz. of water by the end of it.
I also realized that my calves were still a little sore from ice skating two days ago.
Here are today's results:
Mile 1: 4.0 mph
Mile 2: 4.0 mph
Mile 3: 4.0 mph
Mile 4: 3.9 mph
average speed 3.98 mph
average heart rate 133 bpm
I suspect that the first two miles my body was not sufficiently hydrated yet.
I know I never would have figured this out if I had run without a heart rate monitor to notice the subtle changes.
