So being basically in the best place for weather means that there isn’t a huge amount of change in the way I run from season to season. In the summer, it can get pretty hot, so I run early or late.  In the ‘winter’, I use the term loosely, I might wear a long sleeve shirt.  Maybe a hat if it is really cold, under 45 degrees.  Otherwise, slightly more or slightly less water for a run is about the change I see in prepping for a run year round.  The changes in the time the sun is available has necessitated a light or reflective vest depending on my work schedule.  That being said, some people have to deal with mother nature on their runs!! Flowing with nature is a good read about working with the seasons as you run from a runner in Alaska.  This is about as far from sunny San Diego running as you can get.  The similarity of seeing something new in nature for the first time though is great. I love being by the ocean and seeing the dolphins play in the surf, or being on a trail and seeing the rabbits scatter.  Probably my favorite site is seeing the ospreys or hawks glide overhead.  Happy nature running!
