81-Year-Old 'Super López' Defies Aging with 3:39 Marathon

Juan López, 81 and nicknamed Super López, keeps defying age in distance running with a 3:39 marathon and a 4:47:35 50km world record; scientists credit his top-tier VO2 max (52.8 ml/kg/min) and high muscle mass, while he trains 65–120 km weekly and cares for his disabled wife, noting he might aim for records beyond 85 years old.
