  "account": "In 2022, Aleksandr Sorokin set a new world record by running 198.6 miles in a single 24-hour period, nearly matching the distance of eight marathons. This remarkable achievement was made possible by a combination of six key factors: VO₂ max, running form, footwear, nutrition, environmental conditions, and mental fortitude. To delve deeper into what it takes to break distance-running world records, Business Insider spoke with experts and researchers who are pushing the boundaries of human endurance. Among those consulted was Kristian Blummenfelt, an Olympic and Ironman champion whose VO₂ max was recorded at an impressive 101.1. Researchers from Stanford's biomechanics lab also shared insights by creating a digital model of Dean Karnazes, who holds the record for the longest continuous distance run without stopping. The team examined the advanced cushioning technology of \"supershoes\" designed to optimize energy return during long runs. They also investigated the limits of an ultramarathon runner's gastrointestinal system and the impact of hot environments on maintaining core body temperature. Lastly, the mental aspect of such grueling endurance tests was explored by visiting Queens, New York, where they met the front-runner of the Sri Chinmoy 3100 race. This unique event entails circling the same block nonstop for 52 days straight, a grueling challenge that demands immense mental resilience. Through interviews and observations, Business Insider presented a comprehensive look into the science and human spirit behind these extraordinary feats of endurance.",
