⏵ Course guide · North Shore, Lake Superior
Grandma's Marathon runs point-to-point from Two Harbors to Duluth down scenic Highway 61 along Lake Superior's North Shore: gently rolling, slightly net downhill, and fast, with one real test at Lemon Drop Hill near mile 22. I will walk you through the course and the lake's weather wildcard first, then give you a pacing and fueling plan, plus free tools to dial in your own numbers.
These facts come from the official grandmasmarathon.com site and public race listings. Confirm the current year's exact cutoff and registration mechanics before you commit.
This is a fast course by design, but the lake and one late hill both have a say in how your day actually goes.
The course starts in Two Harbors and runs point-to-point down Highway 61 along Lake Superior into Duluth. It is gently rolling and slightly net downhill overall, exactly the kind of profile that produces fast times and a lot of Boston Qualifiers, especially when the lake cooperates with a tailwind.
Near mile 22, the course hits Lemon Drop Hill, a short climb that would barely register early in a race but lands right where fatigue is already setting in. It is the single clearest terrain challenge on an otherwise fast, forgiving course, and runners who have not specifically trained for it often find it costs more time than its modest length suggests.
Lake Superior shapes the day more than the terrain does. A tailwind off the lake can make an already-fast course feel effortless, while a cold headwind can turn the same course into a grind. Check the wind forecast specifically, not just the temperature, in the days before the race.
The temptation on a net-downhill course is to bank time early. Resist it, and save your margin for Lemon Drop Hill instead.
A gently rolling, net-downhill course invites an aggressive early pace, but going out faster than your fitness supports just because the road tilts your way is how runners blow up before Lemon Drop Hill even arrives. Hold your planned effort through the early miles and let the course's natural speed work in your favor without chasing it.
This is a well-regarded BQ course, so if a Boston Qualifying time is the goal, use the race-equivalent calculator to translate a recent race into a realistic goal pace here, then check your full mile-by-mile plan, including a slightly slower Lemon Drop Hill split, with the race-time calculator.

Mid-June on Lake Superior can be cool and ideal or warm and humid, sometimes both within the same race week, so build a plan that flexes.
Set a standard per-hour carbohydrate schedule for a marathon effort, and confirm your exact gel count for your goal time. If race week trends warm and humid, plan to add fluid and sodium rather than assuming the historical cool-weather average will hold.
Lake Superior's wind can change your effective effort more than the air temperature does. A cold headwind adds real work on top of the marathon distance itself, so if the forecast shows wind off the lake, plan slightly more conservative fueling and pacing than you would on a calm day.

Fast. The point-to-point course down Highway 61 is gently rolling and slightly net downhill overall, which along with cool early-summer North Shore conditions is exactly why it has built its reputation as a premier BQ and PR race. The one real obstacle is Lemon Drop Hill, a short climb near mile 22, which is not long but arrives at the worst possible point in the race.
Lemon Drop Hill is a short climb that hits around mile 22, late enough in the race that even a modest grade feels significant on tired legs. It is the one clear terrain challenge on an otherwise fast, gently rolling, net-downhill course, so plan to hold effort rather than pace through it and expect your split to slow slightly there on purpose.
Yes, it is one of the more well-regarded Boston Qualifying courses on the calendar. The point-to-point route along Lake Superior is gently rolling and slightly net downhill, and the biggest variable is not the terrain but the weather: the lake can deliver a helpful tailwind or a cold headwind depending on the day. A well-prepared BQ attempt here should train for Lemon Drop Hill at mile 22 specifically, since that is the one place the course fights back.
Mid-June North Shore weather is genuinely variable: some years bring cool, ideal conditions in the 40s to 50s, others turn warm and humid, and the lake breeze can swing either way. Set your fueling around a standard marathon rate but build in flexibility, work out your gel count for a range of finish times with the free gels per race calculator, and check the forecast closely in race week since the lake's influence is hard to predict more than a few days out.
Grandma's Marathon runs on a capped registration that reliably sells out, with some lottery and early-access mechanics added in recent years. If you are planning around this race, register as early in the cycle as you can and check grandmasmarathon.com for the exact current-year process rather than assuming open registration will still be available close to race day.
Yes, with the lake as the caveat. The course itself is approachable: gently rolling, slightly net downhill, and scenic the entire way along Lake Superior's North Shore. The two things a first-timer should prepare for are Lemon Drop Hill at mile 22, a short but real climb late in the race, and the North Shore's weather variability, which can swing from ideal to warm and humid depending on the year. Train for both and this is a strong first-marathon choice.
