Fewer Than 500 Entries Still Available in 2023 Grandma’s Marathon

(DULUTH, MINN.) — Fewer than 500 entries are left in the 2023 Grandma’s Marathon, keeping this year’s race on pace to be one of the fastest sellouts in the organization’s history.

The fastest Grandma’s Marathon has ever reached capacity was in 2016, when the event was full by December 31. If this year’s current pace continues, race organizers expect this to be just behind that year in terms of all-time early registration success.

“It’s somewhat unprecedented, the demand we’re seeing for this year’s event,” Marketing & PR Director Zach Schneider said. “It’s difficult to compare this year to years when the race was smaller than it is today, but in terms of sheer participation numbers we’re looking at perhaps the biggest race weekend Grandma’s Marathon has ever had.”

There are also 150 entries remaining in the 2023 William A. Irvin 5K and Great Grandma’s Challenge, which allows participants to run both the 5K on Friday night and full marathon on Saturday morning.

The entry fees for each of the available races are as follows, with registration accepted on a first-come, first-served basis:

Grandma’s Marathon (450 spots remaining)

$140 – January 1-March 31

$150 – April 1-June 1
