I am struggling with my running. I'm marathon training again, my long runs are 18-20 mile runs, on these training runs, about mile 5-6, I've been struggling with "runs" of their own type. I've stopped taking magnesium at bed time the night before my long run, but I'm up and out the door (extremely early to beat the heat) before I get my regular business done. I'm hoping Unikey/Dr. Ann Louise, can suggest something to take the night before to avoid this early AM regularity. I don't want to take Imodium AD the night before my long run, but I"m about to think that's what's going to have to happen if this problem can't be resolve in another way.
