(LiveScience) Twelve athletes will embark tomorrow on an extraordinary feat — to run across the United States from California to Maryland, more than 3,000 miles, completing a marathon a day, nearly every day for the next four and a half months.
And scientists plan to tag along, capitalizing on this unique opportunity to study the impact of ultra-endurance running on the human body.
The extreme endurance event could provide insight into how the rest of us mere mortals can better cope with the trials and tribulations of more moderate exercise, the scientists said.
