About This Race

The American Heroes Run stands as a moving tribute to those lost on September 11, 2001, and the heroes who continue to serve our nation. Held annually on the anniversary weekend, this commemoration race offers multiple distance options on a flat, fast 1.05-mile loop course that allows runners to choose their own challenge while honoring our fallen heroes. What sets this event apart is its thoughtful scheduling—each race distance begins at times that correspond to the tragic moments of 9/11: the half-marathon starts at 8:46 AM when the first tower was struck, the 9.11-mile run begins at 9:03 AM marking the second tower attack, and the 5K commences at 9:37 AM remembering the Pentagon assault. This deliberate timing transforms each start into a moment of remembrance. The event's unique structure accommodates everyone from 5K participants to 100-mile endurance runners, with time-based challenges like the 24-hour run and the symbolic 9 hours and 11 minutes option. The flat loop course makes it accessible to runners of all abilities while the multiple distance options create a festival atmosphere where the running community comes together in shared purpose. Race director David Clark emphasizes 'no politics, just patriotism,' creating an environment focused purely on honor and remembrance.

The American Heroes Run utilizes a flat, fast 1.05-mile loop course that provides excellent spectator access and allows runners to see fellow participants throughout their challenge. The loop format makes the event particularly suitable for time-based events, with runners able to gauge their progress and receive consistent support.

The course terrain appears to be relatively flat based on the description as a 'fast' course, though specific elevation details are not provided. The loop design creates opportunities for runners to interact with supporters and other participants, fostering the community atmosphere that defines this memorial event.

Notable Features

The American Heroes Run's most distinctive feature is its deeply meaningful start times that correspond to the moments of the September 11 attacks, creating a powerful commemorative experience. The 1.05-mile loop format accommodates multiple distance options simultaneously, from 5K to 100-mile challenges, with flexible timing options like the 6-hour open start that allows runners to begin and end within a 30-hour window. The event's focus on remembrance over competition, combined with its 'no politics, just patriotism' ethos, creates a unique atmosphere of shared purpose and community healing.
