⏵ Course guide · Carlton to Duluth, Minnesota
The Voyageur 50 sends you out-and-back from Carlton through Jay Cooke State Park to Duluth and back, on rugged, rooty singletrack with roughly 5,000 feet of climb, a course this old (running since 1982) has earned its reputation the hard way. I will walk you through the checkpoints and cutoffs first, then give you a pacing and fueling plan built for a demanding, technical 50 miler. There are free calculators along the way to dial in your own numbers.
These facts come from the official Northern Minnesota Track Club event page. Check the current year details before you commit. Race logistics can change year to year.
The full 50 miles runs on rugged woodland singletrack, roots and rocks underfoot the whole way, out from Carlton through Jay Cooke State Park to a turnaround at Fairmount Park in Duluth, then back the same way.
Becks Road at 17 miles, the turnaround at 24.1 miles, Becks Road again at 31.2 miles on the return, Peterson's at 41.1 miles, Jay Cooke at 46.5 miles, and the finish at 50, each with its own cutoff time. Treat these as real pacing checkpoints, not just cutoffs to survive, they are the clearest signal you will get about whether your day is going to plan.
Part of the course crosses the dalles of the St. Louis River, including the race's own described "iconic Swinging Bridge." This section is a genuine landmark of the route and a good mental waypoint to break the out-and-back into manageable segments.
With roughly 5,000 feet of combined ascent and descent over 50 miles of rooty, rocky singletrack, this is not a fast, runnable course. Expect your effective pace to run meaningfully slower than flat-course math would suggest.
With intermediate cutoffs at 17, 24.1, 31.2, 41.1, and 46.5 miles, you get frequent, concrete feedback on whether your pace is working, use it.
The same technical terrain you cross outbound, you cross again on the way back, often more fatigued. Do not assume your outbound split time will repeat on the return; build in a real slowdown buffer for the back half, especially through the rootier sections.
If you are behind pace at Becks Road (17 miles), you have real time to adjust before the harder cutoffs later. Waiting until Peterson's at 41.1 miles to realize you are in cutoff trouble leaves you far less room to fix it.
⏵ Free tools to plan your effort
A 6:00am start means most runners are on course through the warmest part of a late-July Minnesota day, on technical terrain that already demands more energy than the flat mileage number suggests.
Aim for roughly 60 to 90 grams of carbohydrate per hour while moving and sodium in the 300 to 700 mg per liter range, leaning up if the day turns hot and humid. On rooty, rocky singletrack, eating and drinking takes more deliberate attention than on smooth trail, so build fueling stops into your checkpoint plan rather than assuming you will manage it automatically while running.

Get a training plan built around YOUR fitness and the technical, rooty vert this historic course demands. Summit Line reads your real training, builds the durability a 5,000 foot, 50 mile day asks for, and rehearses your fueling so race day is something you execute, not guess at.
It is a 50 mile out-and-back trail ultra run by the Northern Minnesota Track Club, starting at the Carlton Munger Trailhead in Carlton, Minnesota, running through Jay Cooke State Park to a turnaround at Fairmount Park in Duluth, and back. It has run since 1982, making it one of the oldest trail ultras in the United States.
The race has a 14 hour overall limit from a 6:00am start to an 8:00pm finish, with intermediate cutoffs along the way: Becks Road at 17 miles by 10:45am, the turnaround at 24.1 miles by 12:30pm, Becks Road again at 31.2 miles on the return by 2:40pm, Peterson's at 41.1 miles by 5:30pm, and Jay Cooke at 46.5 miles by 7:00pm.
The official course description states approximately 5,000 feet of ascent and descent over the full 50 miles, on rugged woodland singletrack full of roots and rocks. That is a meaningful amount of vert for the distance, especially combined with technical footing rather than smooth trail.
Between roughly 5,000 feet of vert, technical singletrack with roots and rocks, and a 14 hour cutoff with real intermediate checkpoints to hit along the way, this is a genuinely demanding 50 miler, not a fast, runnable course. The out-and-back format also means you cross the same technical terrain twice, so fatigue on the return trip compounds whatever the course already asked of you outbound.
The intermediate cutoffs give you clear checkpoints to gauge your pace against throughout the day, which is genuinely useful feedback for a first attempt at the distance. That said, the technical, rooty, rocky terrain and real vert make this tougher underfoot than some other 50 milers, so it is a better fit for someone who has already built real trail-running legs, even if the ultra distance itself is new.
It is a notable footbridge crossing the dalles of the St. Louis River that the race's own materials describe as an iconic feature of the course. Crossing the river dalles on bridges like this one is part of what makes the Jay Cooke State Park section of the route distinctive.
With roughly 5,000 feet of vert and technical footing over 50 miles, and a 14 hour window that likely has you out through the heat of a late-July Minnesota day, plan for roughly 60 to 90 grams of carbohydrate per hour while moving and sodium in the 300 to 700 mg per liter range, adjusted upward if the day runs hot and humid.
