First Marathon Training.

Question
I have got into my first marathon. I am 5foot 8 and weigh 250 lbs. I am the strongest guy I know and squat over 600lbs. I have never been into running until lately. I have been running up to 14 miles. What is your favorite tool to use for marathon training. Any guideline. Am I crazy for trying a marathon being such a big guy?

Answer
Well, at your weight, you could be putting yourself into a situation where you could end up with high stress overuse injuries, from taking all that pounding from running.  You may be able to squat 600 pounds, but there is 750-1000 pounds of force being transferred on one leg as you run, with each step you take.  Hence, your body may be maximally strong, but not strong enough to withstand 26.2 miles of grounding & pounding of your joints on pavement.  Since you can already cover 14 miles, I would suggest doing the half-marathon, if running up to that distance isn't causing you any major issues.
