I started to run, but at the half-mile mark I could tell I was much more tired than I was yesterday, and I aborted the run and came home. Apparently my run yesterday put a lot more stress on my body than I realized. My wakeup HR was 51.
The temperature was in the high 80s and a 5-10 mph wind was blowing, a precursor to a storm front that will be arriving tonight and tomorrow. We need the water from the storm.
