DULUTH — It’s already time to start registering for the 2012 Grandma’s Marathon.

Runners can start registering Friday at 12:01 a.m. CDT. The first 10,000 to register will be accepted into the 36th annual Two Harbors-to-Duluth race.

Organizers say the race pricing structure for next year remains the same as this year’s, with no fee increases in any of the weekend’s three races.

The initial marathon entry fee is $80 through Sept. 30. On Oct. 1, the fee goes up to $85.

Next year’s Grandma’s Marathon will be run on Saturday, June 16, 2012.
