Course and logistics

The Aspirus Health Half Marathon is a 13.1 mile point-to-point course that runs along the North Shore Drive of Lake Superior and enters the I-35 interstate for the final miles, including passage through the I-35 tunnels. The half finishes at St. Louis Bay alongside the William A. Irvin freighter. Bus transport is provided for half marathon participants.

The Finden Marketing Tunnel 10k is a 6.2 mile loop that runs through six tunnels on I-35 and returns alongside St. Louis Bay to the same finish area at the William A. Irvin. The 10k uses a closed course and includes live music along the route. This race does not provide bussing; participants are asked to park at the DECC and meet on the interstate overpass near the Depot. Visit the organization's website for the most recent information.
