NorthShore Run - Aspirus Health Half Marathon and Finden Marketing Tunnel 10k
The NorthShore Run in Duluth, Minnesota presents two running races along the Lake Superior shore and through the city. The Aspirus Health Half Marathon is a 13.1 mile point-to-point course that follows the scenic North Shore drive, enters the interstate at Duluth, passes through the I-35 tunnels, and finishes beside St. Louis Bay at the William A. Irvin freighter.
The Finden Marketing Tunnel 10k is a 6.2 mile loop that runs through six interstate tunnels and continues along St. Louis Bay to the same finish area. The 10k uses a closed course that permits running on the interstate and features live music along the route. The Tunnel 10k does not provide bussing; participants are directed to park at the DECC and meet on the interstate overpass near the Depot.
Both races use shoreline roads and sections of interstate tunnels in Duluth and share a finish area by the William A. Irvin. Maps, course details, and event logistics are provided by the organizer. Visit the organization's website for the most recent information.
