The Stephen Siller Tunnel to Towers 5K Run and Walk will be held Sunday, Sept. 25.

The annual run is held in honor of FDNY firefighter Stephen Siller, who died in the 9/11 terror attacks.

Sunday’s race route traces the steps that Siller took when he abandoned his truck at the Brooklyn-Battery Tunnel and ran to the Twin Towers on foot.
