Drinking a lot of water won't help much, in fact it can be dangerous if it dilutes cells too much causing low sodium/potassium levels, hyponatremia, which can and does kill people in extreme circumstances.
Anyone who runs 100 miles a week does need to drink plenty of water. In the form of fresh veggie juices is the best, which is full of minerals. Even straight water is not going to deplete your body of minerals, but you could die from not drinking enough water. You don't get any minerals from WATER anyway. Minerals come from food, not water.
Sipping water is what you should do. Even then a marathon runner is going to lose 6-10 pounds on average.
Sip a little water, then lose 6-10 pounds? Given I was 137 pounds prior to drinking 1/2 gallon of water, and 133 after running 20 miles, your sipping a little water and then losing 10 pounds would have put me at 127. Would you then sip water after that too instead of replenishing? How many marathons have you run?
Anyone running many miles in training, and racing marathons, does need to drink water.
