Hey Marc love you (love Katie more). I'm running my third Chicago marathon this year I also lift full body 2-3 days a week. My question is am I wasting time lifting while i'm putting all those miles into my running? Am I losing gains with all the cardio?

I think this is a GREAT idea. Stimulating the fast twitch fibers will make you a better runner, prevent injuries and prevent muscle wasting
