The question is about weight training for a marathon; the athlete has not run a marathon before but does have lifting experience. Even if you don't want to run a marathon but would like to get back into running, this programming concept can get you there.
I've been sitting on this one awhile. I sat down and mapped out a very general program for myself (if it were me training a marathon). Also, this fit into some of the recommendations I had with some sprinters at London and how they should train.
