Went out for an easy four mile run yesterday. I got started about 5:30. Did a two mile out and back along the San Diego Creek trail past UCI. My goal was to keep my heart rate around 140 bpm (80% MHR). I averaged 142 bpm (heart rate went up at the end into the 150's as I was climbing back to the car). Average pace was 10:30 - a little on the slow side, but that is what it took to keep my heart rate down.
I wrapped up around 6:15. The sun had already gone down. That means that it's time to get out the night running gear. During the days that I run after dark, I try to stick to trails that have no cars - trails like Upper Back Bay and San Diego Creek. Since last winter was the first that I had run, it was the first after dark experience that I had. I tried to be safe by choosing trails without cars, but I was not prepared for the cyclists! My job became figuring out what to wear to make sure I could be seen by people whizzing past me in the dark. I ended up getting a reflective vest, a clip on red LED flasher, and an LED headlamp. I'm after a new headlamp this winter - the old one has given up the ghost, plus it didn't really provide a focused enough beam to light much in front of me. I wear the flasher on the back of the headlamp strap - that puts it about eye level for most cyclists. I also made sure to wear a fluorescent yellow shirt. I think that did the trick, but I'm still a little leery when I hit the trails after dark.
