World’s longest race! Participants run 5649 times around a New York block

New York- It’s the world’s longest certified foot race: a 3100-mile run that takes participants around the same New York block 5649 times. Thousands of people have climbed Everest- but organizers say only 49 have completed the Sri Chinmoy Self-Transcendence 3,100 Mile Race. Runners have completed more than two marathons a day for almost two months, on less than five hours of sleep a night.

They can’t rely on changing scenery to keep them motivated as the route is a half-mile loop on a concrete sidewalk around a high school in Jamaica, Queens. To mix things up a bit, they alternate daily between running clockwise one day and anti-clockwise the next.
