Dehydration Is a Threat to Your Lives

There's a point at which dehydration could become fatal. But an american or training run, you've got no issue because there's always going to be fluid available. And ten % of the field, i'm looking at data here, finish the race, five to eight per cent dehydrated. They don't even come into the medical tent. Unless you were looking specifically for them, you wouldn't know they existed.
