MS Run the US is a 3,100-mile long relay race from Los Angeles, California to New York. The run was started in Brookfield, Wisconsin in 2009 to raise awareness and research funds for Multiple Sclerosis. The organization also raises money to assist those currently living with MS. Ricardo Contreras, who studies Exercise Science at the University of Wisconsin-Milwaukee, participated in last month’s run as a road crewmember. At just 22, he’s already an experienced distance runner and has run in a number of 5Ks. He shared his heartwarming and inspiring experience as a road crewmember in this audio story.
