NEW YORK (WABC) -- The 18th annual Tunnel to Towers Race in New York City was held Sunday in honor of the fallen firefighter Stephen Siller.
The event traces Siller's final heroic steps before he died during the September 11 terror attacks.
Participants started at the Hugh Carey Tunnel in Brooklyn to the former site of the twin towers. 30,000 runners were expected to participate.
The route honors the moments Siller abandoned his truck in Brooklyn and ran through the tunnel towards the towers of the World Trade Center after it was attacked.
Proceeds from the event benefit the Stephen Siller Tunnel to Towers Foundation, supporting first responders and wounded veterans of the Iraq and Afghanistan wars.
