Another day, another record for the upcoming 2025 Grandma's Marathon Weekend in Duluth.

Just yesterday, I shared that the 2025 Garry Bjorklund Half Marathon reached sellout in record time, hitting capacity in less than 18 hours. That's a few days faster than the previous record, which was set for the 2024 event last fall.

As of Wednesday (only a day into the registration period), the other two remaining races were on track for quick starts in registration as well. One big question race organizers had for the 2025 event was how the public would receive the changes made to the William A. Irvin 5K, which were announced before registration opened on October 1.

The new changes included moving the start of the race to 1:00 pm on Friday, instead of the traditional evening race start. In addition, the course route is being modified for 2025 to accommodate some construction along part of the normal route.

The new route for 2025 will bring 5K finishers across the same finish line the half and full marathon runners will cross in Canal Park on Saturday.

Marking and Public Relations Director Zach Schneider for Grandma's Marathon said that while the change was being made due to those construction concerns, if it was well received by the public, it might be adopted as a new long-term format for the race.

Based on the response of registrations, that might very well happen!

Race organizers announced Thursday morning (October 3) that the William A. Irvin 5K sold out in record time, with more than 2,500 people registering in less than 36 hours. This is not only a little bit faster than the previous record, it is nearly two months faster than the previous record, which was in late November!

This now leaves the full marathon as the last remaining race that is open for registration. As of around 8 am on October 3, there were 4,500 entries remaining for the full marathon and 125 entries for the full Great Grandma's Challenge.

The 2025 Grandma's Marathon weekend the weekend of June 21 ,2025, with the 5K being on Friday, June 20.
