The Grandma’s Marathon Course

Overall Course Profile

Grandma’s Marathon is a point-to-point course running from Two Harbors to Duluth along scenic Highway 61 (the North Shore Scenic Drive). While not completely flat, the course is mostly gentle rolling terrain with a slight net downhill—approximately 200 feet of descent from start to finish.

Key characteristics:

• Point-to-point (requires bus shuttle to start line)
• Runs along Lake Superior the entire way
• Mix of open lake views and forested sections
• Generally protected from wind by the shoreline topography
• Well-marked with mile markers and kilometer splits

Mile-by-Mile Breakdown

Miles 0-5: The Start in Two Harbors

The race begins in the small lakeside town of Two Harbors. The opening miles are relatively flat as you leave town and settle into the race. Crowd support is strong from local residents who turn out early to cheer runners.

Elevation: Relatively flat with minor rolling sections.

Strategy: Resist the temptation to go out fast. The first few miles feel easy—that’s the point. Save energy for later. Find your goal pace and lock into it.

Miles 5-10: Scenic North Shore Running

This section offers some of the most beautiful views of the race. You’re running along Lake Superior with water on your right, occasional forested sections providing shade, and the course gently rolling.

Elevation: Gentle rolling with no significant climbs.

Strategy: Settle into rhythm. Check your pace against goal time. If you’re slightly ahead, that’s fine—the course net downhill helps. If you’re behind, don’t panic yet—there’s plenty of race left.

Miles 10-15: The Middle Miles

The course continues along the shoreline with consistent terrain. You’ll pass through small lakeside communities where local support picks up—residents set up water stations, kids offer high-fives, and spectators cheer from their yards.

Elevation: Continued gentle rolling, nothing significant.

Strategy: Stay mentally engaged. These miles can feel monotonous if you let them. Focus on fueling, maintaining form, and staying present. The halfway point is approaching.

Miles 15-20: Halfway and Beyond

The halfway point falls in this section. You’re past the scenic isolation and heading closer to Duluth. The course remains rolling but manageable. Aid stations are frequent and well-stocked.

Elevation: Minor rolling continues, slight net downhill trend.

Strategy: Check your halfway split. If you’re on pace for your goal, maintain effort. If you’re ahead of schedule, resist the urge to push—save that energy for miles 20-26. If you’re behind, assess whether you can make it up or should adjust goals.

Miles 20-23: The Challenge Zone

This is where every marathon gets tough. You’re deep into the race, legs are tired, and the mental game intensifies. The course profile doesn’t change dramatically—it’s still rolling—but fatigue makes every small hill feel bigger.

Elevation: Rolling terrain feels harder now due to cumulative fatigue.

Strategy: Break it down. Run to the next aid station. Count down miles one at a time. This is where your training and mental toughness carry you. Stay fueled, stay hydrated, and keep moving forward.

Miles 23-26.2: Approaching Duluth and the Finish

You’re entering Duluth now, with increasing spectator support as you approach the city. The final miles bring you into Canal Park, Duluth’s historic waterfront district, for a spectacular finish with the Aerial Lift Bridge in view.

Elevation: Mostly flat to slightly downhill into the finish.

Strategy: Empty the tank. You’ve come this far—give everything you have left. The finish area is iconic, the crowd support is strong, and you’re about to accomplish something incredible. Push through to the end.

PR Tips for Grandma’s Marathon

1. Use the Net Downhill Strategically

The 200-foot net descent from Two Harbors to Duluth is an advantage, but it’s spread over 26.2 miles—subtle enough that you won’t feel it constantly. Don’t count on coasting downhill.

Training strategy:

• Train on similar rolling terrain if possible
• Include downhill running in your long runs to prepare quads
• Practice maintaining consistent effort (not just pace) on gentle descents
• Strengthen quads and knees for sustained downhill stress

2. Prepare for Variable June Weather

June in Minnesota can be unpredictable. You might face:

• Perfect conditions: 50-60°F, overcast, light breeze (ideal!)
• Cold start: 40°F at the start, warming to 60°F by finish
• Warm conditions: 70°F+ if heat arrives early (challenging)
• Rain or wind off Lake Superior (less common but possible)

Race day prep:

• Check forecast the night before and adjust clothing
• Bring throwaway layers for the start if cold
• Don’t overdress—you’ll warm up by mile 3-4
• If it’s warm, adjust pace expectations and focus on finishing strong

3. Master the Bus Shuttle Logistics

Grandma’s is a point-to-point race, which means you finish in Duluth but start in Two Harbors. Race organizers provide buses from Duluth to Two Harbors on race morning.

Logistics to know:

• Buses start running around 5:00 AM from designated pickup points
• Ride takes approximately 45 minutes
• Bring throwaway layers for waiting at the start (gear check available but limited)
• Porta-potties at the start, but lines get long—use them on the bus if possible
• Give yourself plenty of time—don’t cut it close

4. Fuel Early and Often

The rolling terrain and 6-hour time limit mean many runners will be out there for 4-5+ hours. Fueling is critical.

Fueling plan:

• Start taking gels or carbs by mile 6-8
• Take something every 30-45 minutes throughout the race
• Use aid stations for water and sports drink even if carrying your own fuel
• Practice your fueling strategy during training—never experiment on race day

5. Use Lake Superior Views as Mental Anchors

When the miles get tough, the scenery provides mental relief. The constant presence of Lake Superior is calming and gives you something to focus on besides fatigue.

Mental strategy:

• Run from aid station to aid station (every 2-2.5 miles)
• Break the race into 5-mile segments mentally
• Appreciate the views—this is what makes Grandma’s special
• Use the approaching Duluth finish as motivation in final miles

How to Prepare for Grandma’s Marathon

Training Plan Essentials

Standard marathon training applies, with Grandma’s-specific considerations:

• Training duration: 16-20 weeks for most runners
• Weekly mileage: Peak at 40-60 miles per week depending on experience
• Long runs: Build to 20-22 miles (or 3-3.5 hours)
• Rolling terrain practice: Train on gentle hills to match course profile
• Tempo runs: Practice sustained marathon pace effort

Grandma’s-Specific Workouts

Rolling Long Run:

Find a route with gentle rolling terrain similar to the course. Run 16-20 miles at marathon pace or slightly slower, focusing on maintaining consistent effort rather than exact pace on the ups and downs.

Downhill Running Practice:

Include sustained downhill sections in your long runs (3-5 miles of gentle descent if possible). This prepares your quads for the net downhill stress of Grandma’s.

Negative Split Practice:

Practice running the second half of long runs at the same pace or slightly faster than the first half. The course profile makes this achievable at Grandma’s if you pace conservatively early.

Travel and Logistics

If you’re traveling to Duluth for the marathon:

• Fly into Duluth (DLH) or Minneapolis (MSP): Duluth airport is small but convenient; Minneapolis is larger with 2.5-hour drive to Duluth
• Arrive Thursday or Friday: Gives you time to pick up packet, explore Duluth, relax before race
• Book accommodation early: Duluth is a smaller city—hotels fill up for Grandma’s Marathon weekend
• Stay near Canal Park if possible: Easy access to finish area, expo, and race morning logistics
• Rent a car if flying in: Makes getting around Duluth easier, though race shuttles handle most needs

Race Week and Race Day

Packet Pickup and Expo

• Held at Duluth Entertainment Convention Center (DECC) on Thursday-Friday before the Saturday race
• Pick up your bib, timing chip, and race swag
• Expo features running gear vendors, nutrition samples, and local sponsors
• Plan to spend 30-60 minutes—not huge but worth browsing

Race Morning Timeline

• 4:00-4:30 AM: Wake up, eat breakfast (2-3 hours before start)
• 5:00-5:30 AM: Head to bus pickup location in Duluth
• 5:30-6:30 AM: Ride bus to Two Harbors start area
• 6:30-7:40 AM: Warm up, use porta-potties, get into corral
• 7:45 AM: Race start

Race Day Execution

Miles 0-8: Run 5-10 seconds per mile slower than goal pace. Let the race come to you. Settle in, relax, enjoy the lake views.

Miles 8-18: Hit your goal pace. Stay disciplined, stay fueled. The course is rolling but manageable—maintain effort, not exact pace.

Miles 18-26.2: This is where you earn it. Keep moving forward. Break it into smaller chunks. Use the aid stations. You’re close to Duluth—finish strong.

Aid Station Strategy

• Aid stations every 2-2.5 miles with water and Gatorade
• Some stations also have gels, fruit, and other fuel
• Walk through stations if needed to drink properly
• Thank the volunteers—Duluth locals are incredibly supportive

After the Race: Recovery and Celebration

Crossing the finish line in Canal Park with Lake Superior and the Aerial Lift Bridge in view is a memorable moment. Take the finish photos, grab your medal, and celebrate.

Post-Race Logistics

• Post-race food and drinks in Canal Park finish area
• Gear check return (if you used it)
• Medical tent available if needed
• Official results posted online within hours

Recovery Timeline

• Immediate (0-2 hours): Keep walking, hydrate, eat recovery snacks
• First 24 hours: Light movement, protein and carbs, elevate legs
• First week: No running for 3-5 days minimum, easy walking
• Second week: Short easy runs if feeling recovered
• 3-4 weeks: Gradual return to normal training

Explore Duluth Post-Race

Duluth is a beautiful city worth exploring after the race:

• Walk along the Lake Superior shoreline
• Visit Enger Tower for panoramic city views
• Explore Canal Park shops and restaurants
• Tour a Great Lakes ship at the Maritime Museum
• Enjoy local breweries and restaurants (you’ve earned it!)

Log Your Race and Lessons Learned

Within 24-48 hours of finishing, record the details while they’re fresh:

• Your finish time and how it compared to your goal
• How you felt at different stages (start, halfway, mile 20, finish)
• What went well (pacing, fueling, strategy, mental game)
• What you’d do differently next time
• Weather conditions and how they affected your race
• Memorable moments (scenic views, crowd support, personal breakthroughs)

These reflections become valuable data for future marathons. You’ll remember lessons learned and apply them to your next race.
