Well I did it. We were starting an hour earlier. I went to bed at 9 PM and woke at 3:30 AM before my alarm and laid there until 3:55 when I got up. We started at 5 AM. I finished 18 miles in 3:07:25 or about 10:25/M. I didn’t push it and tried to do it easy and consist. My heartrate was in the 140s most of the time which is good. Afterwards I was one big ball of sweat. I must have drunk 1 gallon of soda or water.
