Course Description

The point-to-point Grandma's Marathon course loses approximately 100 feet of elevation as it runs along Lake Superior. The course travels on Old Highway 61 along the north shore of Lake Superior. The route is mostly flat with some small rolling hills and one significant incline - Lemon Drop Hill - just prior to mile 22.

The start is just outside of Two Harbors, Minnesota and the race finishes in Duluth’s Canal Park.

Although the course is very fast, the typically warm and humid spring weather may slow some runners. However, if the temperature and humidity are less normal on race day, PRs and BQs will be very achievable.
