Gardner, Horn, Johnson, Pirrung, and McCarthy were automatic team selections by virtue of their top 3 finishes in the Ultracentric National 24-Hour Championship in November 2007. Donaldson, Nelson, Jurek, Karnazes, Allen, and Swenson were selected by virtue of their rankings in non-championship qualifying events in the previous 18 months. Pirrung, at age 59, for the fourth consecutive year becomes the oldest athlete ever named to an open National Team in the sport of Athletics. He is the only runner to have been selected for all 6 of the 24-Hour Run National Teams since the World event's inception in 2003. Pirrung won the inaugural U.S. National 24-Hour Run Championship in 1988, then again in 1991, and has finished second in that event for the past 3 years.

The team's Medical Advisor, Dr. Andy Lovy, was recently honored by the American Osteopathic Association as one of the "Great Pioneers in Osteopathic Medicine.

The team is sponsored by apparel manufacturers Sport Science and Injinji. The team is coordinated and managed by the American Ultrarunning Association.
