Print7 Healthcast: Marathon Heat
Getting to the finish line will be harder this year. There are three heat-related dangers: dehydration; over-hydration, which killed a runner two years ago; and heat stroke. This doctor will be running on Monday and he says danger signs include extreme fatigue.
"Also nausea. Nausea can be a sign you're either overheating or the electrolytes are out of wack and then the worse sign, if you start sweating."Dr. Eric Flint, Mt. Auburn Hospital
Jack Fultz knows what it's like to run in the heat. He won the hottest marathon on record in 1976.

He says that runners need to go slower.
"I am worried about Monday."
"We're from Arizona so it is a little hotter there and we've been training in warm weather."Mike Wares, Marathon Runner
If you were prepared for cooler weather, trade in the tights for shorts and definitely go for a hat, in a lighter color, just like the rest of your clothing.
If you wear a mesh hat that will breath and if you pour water over it, some water will drain through and when you put it back on your head it will be cooler."Paul Astorino, Nike Marathon Specialist

And switch to lighter socks.
"As you're getting hotter during the race, the road is also getting hotter."Paul Astorino, Nike Marathon Specialist
