The Tunnel to Towers Run & Walk Series was created to honor the heroic life and death of Stephen Siller, a New York City firefighter (FDNY) who lost his life on September 11, 2001 after strapping on his gear and running through the Brooklyn Battery Tunnel to the Twin Towers. Honor all of those who lost their lives on September 11, 2001 and support our first responders and military who make extraordinary sacrifices in the line of duty! For more information on the Stephen Siller Tunnel to Towers Foundation please visit T2T.org.
This will be the 8th year in Siouxland, and we are excited to once again bring together the community to honor first responders, remember 9/11, and raise funds for the Tunnel to Towers programs.
