Not too long ago one of the trends in fitness events was color runs.

They were 5K run/walks in which participants had colored powder thrown onto them at various points along the course, so that by the end of the event they looked like a human rainbow.
These color runs drew big crowds but I never felt the urge to participate in one. Getting covered with colored powder has never appealed to me. Neither has—as a like-minded running friend of mine once said as the reason she never did a color run—having to spend the rest of the day blowing red, green, and blue snot out of my nose.
But perhaps the main reason that I never had the urge to do a color run is that I have been doing them on a near-daily basis for more than 25 years now. In one way or another, just about run or dog-walk that I go on is a color run.
There is the beautiful sky during the daytime and the stars at night. The bright leaves during autumn and bright flowers during spring and summer. The red cardinals, brown deer, green turtles, and countless other critters seen year-round while I am out getting some fresh air and exercise.
I recently read a post in which the author said that going for a run or walk outdoors is to be witness to a thousand miracles. Miracles that, I might add, come in all kinds of colors.
