The Tunnel to Towers Run & Walk honors the memory of Stephen Siller, a New York City firefighter who died on September 11, 2001. The event supports first responders and military personnel who make significant sacrifices. Participants can walk or run, and first responders lead the start. Finishers receive medals, with awards for top placements. The event offers a chance to fundraise for the Tunnel to Towers Foundation, and donations are accepted post-event. Safety measures include on-site medical staff and a flat course in Big Pine Community Park. Registration is available online or on the event day.
