I just started running. When I run long distances (8 miles) near the end I feel lightheaded and dizzy. Why?

Because oxygen is rapidly being used to keep your body going,and less of the oxygen gets to your head as usual.

its probably dehydration. always drink water on long runs. If I go anything over 4 miles, I carry a water bottle with me.

u r most likely dehydrated at the end of your run. make sure you drink water. Also practice to build up your stamina
