TL;DR: The 2026 Tunnel to Towers Orlando 5K Run & Walk is coming to Cranes Roost Park in Altamonte Springs on Saturday, September 12. The event honors the sacrifice of firefighter Stephen Siller and other 9/11 heroes, military members and first responders. As the presenting sponsor through the Central Florida Buick GMC LMA, Buick GMC dealers are proud to support an event that raises funds for the Tunnel to Towers Foundation and its mission to help America's heroes and their families.
Rarely open to visitors, Milford covers 4,000 acres and features nearly 150 miles of roads for testing GM vehicles. Guests at the event were offered a self-guided tour of the facility, which includes a 2.9-mile racecourse, steep hills, both paved and dirt roads, and a 67-acre swath of blacktop known as Black Lake.
