The Self-Transcendence 3100 mile race is the world's longest certified footrace. In 1996 Sri Chinmoy created this event as a 2,700-mile (4,345 km) race. At the award ceremony that year he declared that the 1997 edition would be extended to 3,100 miles (4,989 km).
This multi-day race is hosted by the Sri Chinmoy Marathon Team and takes place in Queens, New York in the United States from June–August every year. The course is 3,100 miles (4,989 km) long. Runners negotiate 5,649 laps of one extended city block in Jamaica, Queens.
The runners have 52 days in which to complete the distance, running from 6 a.m. to midnight, an average of 59.62 miles (95.95 km) every day. The prize is typically a T-shirt, a DVD, or a small trophy.
The race distance is the distance from the west to the east coast of the US plus 11 marathons. Only runners with proven ultra-running experience may compete, for their own safety. The race is run every day, changing direction each day, whatever the weather, which has ranged from 38 °C (100 °F) heat to torrential downpour—runners sometimes carry umbrellas. Competitors run among people going about their everyday lives, dodging pedestrians and cyclists.
