Leonia, New Jersey, sits on undulating terrain where residential streets wind through a densely settled area. The Leonia Rush threads through this environment, covering 1.2 mi with 11 corners that demand precise car control. A significant 53 m height difference across the lap forces drivers to maintain momentum over the rises to avoid losing speed. This circuit, which plays free in the browser with no account and no install, passes near Stanley Gallone Park and requires a high level of technical skill to navigate the tight transitions.
