The Grandma's Marathon course
A point to point along the north shore of Lake Superior into Duluth, and one of the most reliable Boston qualifying courses in the country. Mostly flat with a gentle net drop, and a scenic, low-stress route.

- Flat
- Distances
- 5K, Half marathon, Marathon
- Weather on race day
- June on Lake Superior is usually cool, which is the point. The lake keeps race morning temperatures down even when inland is warm.
What to train for
A spring build in cold weather sets this up well.
Because the course is fast and the weather is usually kind, this is a legitimate place to chase a qualifying time.

Your build to race day
Taper
Tapering for the Grandma's Marathon
Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course is flat, so pacing decides the day: rehearse your goal pace in short segments during race week. With the race on June 19, 2027, your taper starts around June 1, 2027.
