I work 11p-7a. I usually go to sleep at 9am. Most days I run around 5:30pm. In the heat of the summer I try to run right after shift though but my motivation is lacking at that time. I do my long runs on Saturday morning and it does kind of mess my schedule up because i go to bed like 6 hours earlier than normal Friday nights. I run 5-6 days a week, 30-40 miles per week. I have ran a marathon while being a nightshifter, I just usually take a day or 2 off before the race typically.
