re: Workout time and why?

Indeed. Wake up at 4:30 sharp and am at Lafreiniere or the levee by 5. I do a lot of Crossfit-based stuff on the running trail for time (IE: As many rounds in 20 minutes of 1/4 mile run, 25 prisoner squats, 25 calf raises, 25 crunches) so I stop at each 1/4 mile point and there's no one there to say anything about it. Got 6 and a quarter rounds done this morning. I do hill sprints at the levee twice weekly and there's no one in sight.

Like Jocko says - up before the enemy. It has its benefits for sure.
