What is a Tunnel To Towers Run & Walk? 
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 www.t2t.org.

This is our inaugural year for the T2T Denver 5K Run & Walk and we are excited to bring together the community to honor first responders, remember 9/11, and raise funds for the Tunnel to Towers “In the Line of Duty” programs.
