Over 60 athletes completed a 3 day charity run known as the 9/11 Promise Run. This event honors the inspiring victims and heroic first responders of the September 11th, 2001 attacks.

The groups covered a 240-mile journey from the Pentagon to Ground Zero in only 72 hours. Each runner was committed to cover approximately 30 to 35 miles over the 3 day period (September 9th -11th). This year, participants raised over $65,000 for Hope for the Warriors- a nonprofit organization that aides post 9/11 service members, veterans, and their families to reestablish their sense of self and hope.
