SIGN UP HERE LIME ROCK MOUNTAIN The "Mountain Course" at Lime Rock Park (Lakeville, Connecticut) is a legendary, never-completed track extension originally planned in 1957. While bulldozed and mapped, it was deemed too expensive to pave for racing. Today, it survives as a virtual track in racing simulators and an active cycling route. The Mountain Course: By the Numbers Length: \(\sim 2.93\) miles (compared to the standard \(\sim 1.5\)-mile circuit) Turns: 11 turns Elevation Change: 200 feet Frontstretch: \(\sim3,000\) feet Real-World Use Cases Because the mountainous terrain and heavy tree coverage make it financially prohibitive to pave for automotive sports car racing, the track's footprint is utilized for off-road cycling and mountain biking.
