Think about what happens to your body when you run a marathon, then answer these five questions:
1) Should you replace the water lost with sweating, yes or no?
2)How should you replace the water lost, all at once, continually during the race, or after the race?
3) Should you replace it quickly, slowly, or not at all?
4) Does there need to be electrolytes in the water? What about glucose?
5) Is gatorade good for you or detrimental to your health?
