The Science of Distance Running

This week Reactions is taking a look at the chemistry behind marathon running. The science that goes on in athlete's bodies is pretty neat. Athletes push their bodies for miles and deal with cramping, dehydration and every runner's worst fear: that extreme form of fatigue called "hitting the wall." Why is endurance running so difficult? With the New York City Marathon kicking off this Sunday, Reactions runs through the science of distance running: why muscles burn, how sweat cools the body and the chemistry of runner's high.
