No Overflix. Nineteen-year-old Zach Bates told his mother at graduation that he wanted to run a 100-mile ultramarathon before his 20th birthday. Surprised, she reminded him that his farthest cross-country race had only been 5k. Undeterred, he continued to speak his mind and vision to run a 100-mile race before he turned 20. Seeing his determination and knowing her son's unique ability to deeply focus- due to autism- she decided to let him run and see where he could go.
