Fade to gray

Took a quite colorful picture of the setting sun when waiting for the train after swimming. But decided for the monochrome version.
Darkness dropping in.
My legs are aching, my mind is tired and my couch calls me. Yesterday 3.5 hours cycling, today only 2 hours but my legs protest anyway. Plan to cycle 3.5 hours tomorrow. Wish me good weather!

PS: Sorry when I didn't comment much on other pictures lately, hope that I won't be that busy soon again.
