Family schedule comes before running schedjule

Well, I didn't get my run in today. My wakeup heart rate was down to 59 and I was planning on running, but a last-minute change in my family schedule prevented me from going out. Actually, I could have gone running as it was getting dark, but I was too tired to go that late in the evening. Darkness comes about 9 pm Mountain Daylight Time. When I was younger (mid 40s), I had no problems running late in the evening, but I can't do that anymore. One of the problems with getting old :)
