Did a heavy run with added distance to give 2.4 miles

I left earlier and finished my run a few minutes before it became dark. There was one car in the parking lot when I drove away. I added a bit to my distance and did about 2.4 miles. I took no rest breaks during the run. I wore 4 layers of clothing, same as in my previous runs. My hands, though, were cold because I wore my lighter gloves. I put my hands in the pockets of my nylon jacket during my walking phases; during my jogging phases, I wiggled my fingers to get some heat generated.
