In the 1970s, a 24-hour relay craze took place at high schools, colleges and running clubs. By 1972, Runner's World Magazine, in Mountain View, California, was publishing results along with some standardized rules for these relays participated by hundreds of runners. The Washington and Baltimore Road Runners Clubs were early adopters the relay format when they established a 24-hour 10-man-team relay race in 1970 on the track at Mullins Field in Fort Meade where participants would run one-mile legs. The event would eventually expand to 50-mile and 100-mile solo races competed by many of the best American ultrarunners of the time.

In 1983, two elite ultrarunners in America became inspired to give a try at breaking the world two-man 24-hour record on that track at Fort Meade in Maryland. These ultrarunners were Neil Weygandt and Dan Brannen.
