My heart rate this morning was 57, after almost 9 hours of sleep. I felt great and looked forward to a good run. During the morning we had some snow, but the air temperature was in the high 30s (F), and the snow melted almost as fast as it came down. When I left for my run about 3 pm, the shade temperature was 37 (F). When I returned from my run, the temperature was 32 (F). There was a wind of about 5 mph, and the wind-chill made it seem colder. I wore my usual three layers and long pants, and those layers were sufficient.
For the first two miles, I used a ratio of 115 left-foot-steps running and 66 lfs walking. I felt great during the two miles, but I started to get tired, and I switched to 66 lfs running and 45-50 lfs walking. During the last mile, I walked most of the distance. I felt fine while walking. It was only during the running that I felt the stress of the run. During the past couple of weeks, I only did one good 5 mile run and a second run of 1.5-2 miles or so during each week. I think my performance has declined during that time, and it will take a couple of weeks to get back to doing 5 miles and feeling fine. After I reach the point of feeling fine during the 5 miles, I'll slowly increase my mid-week run and my weekend long run back to the 7 miles I had achieved about a month ago. My Monday/Tuesday run is frozen at 5 miles.
Tomorrow is going to be very cold compared to today, with tomorrow evening going down to single digits. I'm thus glad I ran today.
