I haven't started training yet, I am currently just starting to rebuild my base, but I am starting to read the articles about marathon training, and can't seem to find anything about how far or long to make my training runs.

I used to run marathons, and I would like to try and qualify for Boston again. When I was serious about my training, my training schedule would range from 50 to 80 miles per week, from the start of the cycle to race day. I don't want to go there again.

So after reading Mark's article I will be running 4 - 5 times a week. 2 - 3 aerobic threshold runs, 1 interval, 1 race pace. What I would like to know from other primal marathoners is where do you draw the line? and is that line at distance or time?
