Grandma's Marathon Pace Calculator & Race Plan
Grandma's Marathon runs along the North Shore of Lake Superior from Two Harbors to Duluth. It's a fast, net-downhill course that draws a lot of BQ chasers. The scenery is beautiful and the June weather is usually cooperative, though Lake Superior can create its own microclimate.
The course has gentle rolling hills in the first half before flattening out for the run into Duluth. It's a course that rewards patience. Our splits give you a plan that holds back slightly in the rolling early miles.
