I did a quick 5 AM "dark ride," except that it's not really so dark out at 5 AM anymore! Actually didn't get out until about 5:15, so we opted for the short, flat route, instead of the 2 ten percent grade hills ride that is a little longer.
Ten and a quarter miles, with the sun coming up around 5:30. Got back by around five 'til six, hopped in the shower, drank my coffee and grabbed a quick yogurt and was off to work at 7:00.
I love going out on these early AM rides. People here get up so late, there's hardly anyone up and about. Now that it's getting light earlier, I did see 3 riders today, one of them when it was still kind of dark, with no lights. Those ten miles feel as good as 30 at that time of the morning.
