5:32 a.m.

Perhaps you're thinking that you'd like to get up and do a sunrise run but it's too hard in the lightest 3 months of the year. I hate to use an alarm clock, but maybe, like me, you have a brain that can wake itself up a few minutes before the alarm goes off. Just setting the alarm is enough to set the brain, and then you never hear the alarm. 

Another technique, and I like this better, is to sleep with the windows open and wake up when you hear the birds. How can you make your sleeping brain react to something you hear, something that's so much gentler than an alarm clock? I don't know, but try just thinking about doing that. It's worked for me lately, but only after using the alarm for a while. At first, I was waking up to the alarm. Then, I adjusted and woke up just before the alarm went off. Then, I readjusted and woke up when the birds "went off." 

This is an excellent arrangement for me. The birds seem to come on about 40 minutes before the sunrise time. That gives me 15 minutes to get from bed to car, 5 minutes to drive to my starting point, and 15 minutes to get to the place you see in my photograph... with 5 extra minutes for gazing into the sky before the sun crosses into view.
