Is it okay to do all AeT workouts fasted?

    I’ve been building up my running, and have reached a point where I’m running 6 days a week. Mostly out of habit, I run in the morning before eating breakfast. I feel fine during and after workouts, but have seen training advice in other books/articles that suggest doing some fasted training – but none of them seem to suggest doing it all fasted. Is there any problem with doing all of my AeT workouts in a fasted state? (I do eat a small snack before workouts that add intensity above AeT).

    If you are recovering between workouts and feeling adequate energy during these base aerobic runs then you are fine doing this. Top athletes I work with almost all their Z1-2 runs in a fasted state. If the runs get over 2-3 hours then you may need to carry and emergency snack of some sort. But, even those longer run will get easier to do in a fasted state as you adapt. To speed recover I suggest eating right after you finish. I notice that if I miss this feeding window after a long fasted run, I’ll feel that workout fatigue for as much as 48 hours where as if I eat immediately after I finish I’ll bounce back in a day.

    Hi Scott,

    have a question on that eating immediately after exercise thing you mentioned.
    Does that intake have to be proportional to workout duration/total calory burn? In the book you mention to take in 100-200 calories (if i remember correctly) but do not distinguish more specifically between different workouts (durations). Any rule of thumb for this?
