David Miao took up running at fifty-four, in Flushing, Queens, because he was putting on weight. He had never heard of a gel, a drop bag or a pacer. At his first marathon he picked a stranger who was aiming for three hours thirty-five and copied him exactly, stopping every time he stopped, even at water he didn't want. At the finish people kept telling him he killed it. He had no idea what they meant. His wife Karen came that day only to support him. It was the end of January and too cold to stand around for hours, so she ran the half marathon. She had never run a step. She hasn't stopped since. Less than two years later, in October 2020, David ran his first hundred-miler: ten loops of a ten-mile course in a Long Island forest, with no vest and no bottle. He won it outright. The next summer, at the Great New York 100, he ran in one-dollar socks while other runners laughed, and finished second in nineteen hours. He was the first member of his club, the Misty Mountain Runners, to run fifty miles and the first to run a hundred, he says, and the club has followed him to the start lines ever since. In 2022 he finished all four races of the Grand Slam of Ultrarunning, after discovering three races in that he had never registered for the last one, Wasatch. He emailed until they let him in, five days before the start. In 2023 he ran Cocodona, 250 miles across Arizona, with Karen pacing the last sixty. Five miles from the finish he ran ahead to break ninety hours, crossed the line, and ran straight back up the trail to bring her in. That September they ran UTMB around Mont Blanc, and nine days later started Tor des Géants: 330 kilometers through Italy's Aosta Valley with about 24,000 meters of climbing. Karen had won a lottery spot and David hadn't, so he paid double for a charity bib to run it beside her. They finished one second apart. A Chinese gear brand, Kailas Fuga, took him on after that. This year, at sixty-one, he has run Cocodona again with Karen, UTMB, Tor des Géants for a third time and, in October, The Mammoth 200. He tells Mark about the aid-station captain at The Mammoth who threw him out after six hours of sleep, the half-hour nap near the end of UTMB that he says cost him the lead in his age group, running the Bay Area 100 in nothing but shorts, and why Karen made him carry six liters of water up a mountain. He also gives Mark his honest take on the big race companies, UTMB, Aravaipa and Destination Trail: what each does well, and where the aid-station food could be better. He doesn't go to a gym. He barely sweats, so he barely drinks. And he has a simple case for anyone over sixty: get on the trails, build your balance and your ankles, and keep running so you keep the muscles you use. This is David's first podcast ever. He had never told these stories on a mic before, and we're grateful he said yes.
