(Jan. 2019) On December 19, 2019, Mark Courtney completed his daily run for the 14,609th day in a row. That's 40 years with nary a day off. Courtney's impressive in many other ways. He has run 40 straight Boston Marathons, and has a marathon PR of 2:28:48 at Chicago. Now 63 and living in Grove City, PA, he continues to operate a road-race timing company--Runner's High. His running allows him to eat somewhat indiscriminately. "My diet includes beer and ice cream," he says. "Though rarely at the same time."
