Ian Mackay was paralyzed 14 years ago in a bike accident, leaving the active 26-year-old with the physical abilities of an infant. Today, he’s traversing hundreds of miles in an Invacare TDX SP2. For Sports Illustrated, Joseph Bien-Kahn tells Mackay’s inspiring story and offers an account of his latest challenge: breaking a world record for the greatest distance covered in 24 hours by a motorized wheelchair.
