On June 21, 2025, one of the Midwest’s most iconic and beloved races returns: Grandma’s Marathon in Duluth, Minnesota. Known for its fast times, flawless logistics, and unforgettable scenery, this race is more than just a regional favorite – it’s a rite of passage for many serious marathoners and a hidden gem for those chasing their next PR or Boston qualifier.

And yes – you can literally ride a train to the start line. Welcome to Grandma’s.

The Course: Flat, Fast, and Hugging the Shore of Lake Superior

Grandma’s Marathon is one of the flattest and fastest races in the country, and the 2025 edition will once again start in the tiny town of Two Harbors, Minnesota. From there, runners will follow Scenic Highway 61 along the north shore of Lake Superior, all the way into downtown Duluth.

The route features a net downhill profile with just a few gentle rollers, flanked by tall pine trees, wide-open lake views, and the occasional bald eagle overhead. If the weather cooperates – and it usually does – expect crisp temperatures in the 50s, light winds, and perfect race conditions.

Every mile of the 26.2 journey brings postcard-worthy views, but the final stretch through Canal Park, with spectators crowding both sides and the finish line in sight near the historic Aerial Lift Bridge, might just be one of the most emotional finishes you’ll ever experience.

Take the Train: Race Day Magic on Rails

One of the most charming and unique aspects of Grandma’s is the North Shore Scenic Railroad train, which shuttles runners from Duluth to the start in Two Harbors. Watching the sun rise over the lake as you ride through the forested corridor with fellow runners adds an unforgettable sense of calm before the challenge ahead.

It’s a quiet, nostalgic, and oddly magical way to begin a race day – and just one of the many touches that makes Grandma’s feel special.

The Vibe: Local Hospitality Meets Big Race Energy

Grandma’s draws over 20,000 runners across its full marathon, half marathon (Garry Bjorklund Half), and 5K – but it never feels overwhelming. It’s the best of both worlds: big enough to deliver professional organization and deep fields, yet small enough to feel personal and welcoming.

The event is deeply rooted in Duluth’s community. Named after the original sponsor, Grandma’s Restaurant, the marathon has grown into a weekend-long celebration that includes live music, an enormous spaghetti feed, and the kind of volunteer support that makes every runner feel like a local.

Chasing Boston – and More

Year after year, Grandma’s is one of the top Boston Marathon qualifying races in the country, thanks to its elevation profile, cool weather, and smooth logistics. Whether you’re gunning for a sub-3:00, trying to break 4, or simply aiming to cross that line upright, this course is built to help you achieve your goals.

Elite athletes come for the speed, 50-staters come for Minnesota, and everyday runners come for the experience – and almost everyone leaves thinking, “I’d run that again.”

Why June 21 Is a Must-Run Date

If you’re looking for a marathon that blends natural beauty, historic charm, and a runner-first experience, Grandma’s Marathon should be on your list. With its flat, fast course, gentle lakeside breezes, and a finish line framed by cheering crowds and nautical beauty, this race is more than a marathon – it’s a story you’ll want to tell again and again.

So lace up, take the train, and get ready to fly down the shore. On June 21, Grandma’s Marathon will once again prove why it’s one of the most beloved races in the U.S. – not just for the time on the clock, but for the memories that last long after the final mile.
