KQDS Staff,

DULUTH, Minn. — Registration for the 2025 Grandma’s Marathon weekend opens Oct. 1 at 7 p.m. on GrandmasMarathon.com.

The William A. Irvin 5K will have a different court next year.

It’ll start on Harbor Drive by the Irvin before headed to Canal Park Driver, underneath the main marathon finish line structure, and then ending in Bayfront Festival Park.

The change is because of planned construction outside the Lake Superior Maritime Visitor Center.
