Body Systems: Marathon

What would cause a marathon runner to collapse?

A marathon is a 26.2-mile race. People often train for months leading up to the race in order to successfully complete this type of long-distance running challenge. Sometimes, runners aren’t able to finish the race, or runners collapse and die shortly after the race. Your challenge is to use your findings from research articles, data sets, and other class activities in order to determine and explain what is causing marathon runners to collapse and sometimes die.
