On 9/11, Stephen Siller, an off-duty firefighter, ran through the gridlocked Brooklyn-Battery Tunnel with some 60 pounds of gear on his back to reach ground zero, where he was killed. His namesake foundation organizes many fundraising events, including an annual 5k run through the tunnel to the World Trade Center.
So sad story. Just having read that I found out that the annual race was held, for coincidence, today. It seems that has grow a lot, 30000 people.
