Named after Grandma's Saloon & Deli, the newly opened Duluth restaurant that put up the race's entire $600 budget in 1977 when no other local business would sponsor it. The course runs point-to-point along Lake Superior's North Shore into Duluth, net downhill and fast, with June timing that keeps a summer race cool.

The bottom line
This is a course built to give time back.
Grandma's Marathon is a strong choice for a fast time on tired legs, and the route gives back elevation for most of the 26.2 miles. The tradeoff is your quads, which will feel the descent in the closing miles.
