Summary
Sporting history was made at this year’s London Marathon. Sabastian Sawe became the first man to finish a competitive race in less than two hours. How are elite athletes getting so much faster? We investigate how runners are harnessing the science of physiology and the technology of shoes to increase their speed. Plus, how anybody can train for a marathon—or just get fit fast.
