Answer:
Runners burn roughly 100 calories of glucose for every mile of the marathon. That means you will have burned your entire supply of glucose after 32 km and will start to rely almost exclusively on fat for fuel. Because fat provides less energy per unit time than glucose, you will have to slow down.
