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 race, which lasts several weeks, is hosted by the Sri Chinmoy Marathon Team and takes place in Queens, New York in the United States in the summer 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 - 164th Place to Abigail Adams (84th) Avenue to 168th Street to Grand Central Parkway — a distance of 0.5488 miles (883 m), while the streets are in normal use. 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.
