For all you runners out there who know what it takes to run a marathon, consider this...an athlete carried two car tires on his shoulders in a marathon in Austin, Texas on Sunday.
Michael Ball of Oklahoma says he wanted to do something that would push his mind and body to the absolute limit.
The 23-year-old runner incorporated the tires into his training a year ago. Though he admits running with tires would be tough, it was something he was comfortable with.
Over 10,000 runners took part in the 26.2-mile race.
