Note
The forecast for today made it clear that it made no sense to try for any mapping, with good and increasing chances for rain as the day went along. I had hoped to get out by late morning for some running and planned for intervals, but as it worked out, the morning was quite busy with work, and so it wasn't until very early afternoon that I was ready to go. By then it was already sprinkling intermittently and the skies off to the west looked distinctly unpromising. I figured I would at least get started, and if/when I got too soaked and cold and things were miserable, I would call it a day.
I started out with a light jacket while a few raindrops were falling, and then the sun came out, so I ditched the jacket. Then the rain picked up again and the sun went away, so I retrieved the jacket. Right as I was finishing warming up, the sprinkles stopped again and the sun started peaking through, so once again I ditched the jacket, and got started on the workout.
And in the end it worked out great, despite sprinkles constantly starting up and stopping, It never got bad, and it was almost the opposite--refreshing. A bonus from the light rain was the trails became moist and the sandy parts more compact, with zero dust.
Only saw one other person--a mountain biker--the whole time I was out.
