The Carbon Footprint of Marathon Runners: Training and Racing.

Unlabelled: Marathon running leaves a significant carbon footprint regarding CO emissions; for example, 37 percent of New York Marathon participants travel internationally to New York. The aim of this study is to estimate the CO footprint of a person training and competing in a marathon; we will also propose methods to minimize the CO footprint because of transportation. In addition, we also examine the influence of food practices and hygiene on training and racing a marathon.
