Today was a cold day with snow flurries during the night and early morning. I went running at 4:30, and since we're off daylight savings time, the sun was behind the Oquirrh Mountains when I started my run. I was back to my car an hour later and it wasn't quite dark yet. Because of the mountains, the Salt Lake valley has a long dusk period.
I wore three layers, two short-sleeved t-shirts and my long-sleeved nylon jacket. I didn't check the temperature before I left home, but the temperature when I got back was 33 (F). My body felt fine, but my hands were cold because I didn't wear gloves.
I had a great run, my best run in several weeks. I felt strong during the run and took no rest stops. I'm still running and walking for 60 seconds each.
