Of course, right now, after having taken so much time off, I don't run far (3 miles a week or so in 1 mile increments as I'm building back up and don't want to get injured again) so your distance might make a difference.
My suggestion... jump back into EMF. Get your carbs down. And WAIT before you run. As a runner I know how hard this is. If you wait and get to ketosis, then start running again, you may find it's not as difficult as it is now. Just a suggestion. Take it or leave it. But it works for me.
