I've found that I've been doing a lot more of it... I had to resort to running at night because I can't find any other time throughout the day to run. Between the short days, spending time with my family and work stuff, this is really the only time that I have available for "me time". I've just learned how to dodge headlights. Needless-to-say, it is very relaxing and, well it also fits well into my schedule.
Basically, I run while others sleep. I've done quite a bit of night running these last couple of weeks. The first time was the most awkward really, because I didn't know what to expect. After I realized how relaxing it was, I discovered that this is really the best time to run. Jen has a head light that she uses for working around the barn yard after dark and I strap that on my head and go. I try to wear as much white as possible so that people can see me and my shoes reflect pretty bright, so it's fairly safe. I've asked Santa for some reflective clothing this year, so we'll see...
Here is my favorite late night path:
Basically, I park at my friend's house (thanks Tyler) and just go... I showed up at his house tonight @ 10:15 and took off running. I got back around 11:15 and then came home. The night after my company Christmas dinner, I actually ran a longer version of this loop and didn't get back to my car until about 1 am. :)
It's funny because a lot of the cops doing their rounds at night probably all refer to me as "that crazy guy with the head light" on their radios. I just wave at them... :)
