There will also be FREE return shuttle bus service provided for participants and spectators on race day. The buses will run continuously from 8:00 a.m. to 3:00 p.m. on race day.

You will receive an official, clear plastic gear bag at race packet pick-up. A label with your race number is provided in your race packet envelope and must be placed in the designated space on your bag.

Gear bags must be dropped in the appropriately numbered containers near the start corral entrance. You must drop your gear bag by 7:15 a.m. to avoid delays getting into the start corral. No gear bags are permitted in the start corral. Please plan to wear warm layers on race morning. Extra clothes can be discarded in the start area prior to the race – True North Goodwill will reuse or recycle all clothing left behind.

Participants may pick up their gear bags in the secure finish area. You may pick up your gear bag before collecting your post-race food, if desired.

IMPORTANT: Unofficial gear bags (including backpacks) are not permitted and will not be accepted. Do not leave valuables in your bag. Race officials are not responsible for any lost items. All bags are subject to inspection and should not be left unattended.

NEW IN 2025: Hydration packs or vests, fuel belts, and hand-held water bottles are allowed. Hydration packs or vests are limited to an overall capacity of no more than 8 liters (8L), and a water bladder capacity no more than 1.5 liters (1.5L), if applicable. Any items brought to start line areas by participants may be subject to search by law enforcement. 

To help create a more efficient start experience, Grandma’s Marathon uses a staggered start process with three separate corrals for participants.

Based on goal finish time submitted during registration, participants will be assigned to either Start Corral A, B, or C. The corral assignment will be printed on each participant’s race bib.

Corrals will have separate start times, listed below:

Corral A: 7:45 a.m.
Corral B: 7:55 a.m.
Corral C: 8:05 a.m.

After the bus or train unloads near the start, participants MUST drop  their gear bag at the trucks near the entrance to the Sonju Two Harbors parking lot on the right (along the roadway). Toilets will be available in the parking lot prior to the start of the race.

When participants are ready to enter the start corral, please do so from the parking lot side. Please use the access points outlined below to enter the corral you are assigned to on your bib (if you’re moving back to Corral B or C, use the lane of the corral in which you intend to start). Volunteers will be on site to assist.

• Corral A should use either the pathway at the far west side of the parking lot or the middle driveway to the parking lot, marked by signage. NOTE: These participants will be directed to use a grassy walkway to access their corral.
• Corral B should use the middle driveway to the parking lot, marked by signage. NOTE: These participants will be directed to use a grassy walkway to access their corral.
• Corral C should use the driveway closest to the gear bag dropoff trucks to enter the start corral, marked by signage.

Participants may choose to move BACKWARD in the corral system, but in no scenario can a participant move FORWARD (i.e. if you’re assigned to corral A, you can choose to start in either B or C).

IMPORTANT: Please expect and plan for congestion and long lines at the start line, especially for the portable toilets. There will also be speakers playing music and announcements – if noise is a sensory issue, please plan to bring ear plugs to use until after the race has started.

Experienced pacers, presented by ASICS, will be available in the following corrals at the listed goal times:

Corral A: 2:55, 3:00, 3:05, 3:15, 3:20, 3:25
Corral B: 3:30, 3:35, 3:45, 3:50, 4:00
Corral C: 4:05, 4:20, 4:35, 4:50, 5:00, 5:30, 6:00

Signs displaying pace times will be along the side of the start corral. Pace team leaders should be near the sign of the corresponding time.

There will be plenty of portable toilets, as well as water and medical aid, available to participants at the start area in the parking lot of Sonju Two Harbors.

NOTE: Please be respectful of our neighbors along the racecourse and help keep Minnesota’s North Shore pristine by using designated portable toilets ONLY. Participants doing otherwise run the risk of disqualification.

The Grandma’s Marathon start area is lined on one side by trees and private property and on the other side by railroad tracks and Lake Superior. Due to this confined nature, as well as a lack of available parking, spectators are not encouraged at or near the start line.
