dehydration is a brutal part of running long distances.

Answer 2

you shouldnt be scared bc as long as your training and not overdoing it you will be fine.  some people that dont train well then go out to run a half marathon in the heat can get heat strokes.  dont be afraid its not common.

Answer 3

well maybe they are over doin it liek as well y do players die on teh football pitch

Answer 4

most of the causes are because the heat is too intense, they are dehydrated or they had some kind of health problem such as heart disease or if their family has a high risk of heart attacks.

Answer 5

All of the above is correct, but there's another reason for death after a long run, and that is hypothermia.  Even while it's hot outside, after a long run, your body can actually loose so much heat that it'll shut down the heart.  This is why most runners are greeted at the finish line with thermal blankets.

Answer 6

because of dehydration
