Looking for an easy first-time marathon or speedy Boston Qualifier? You’re in the wrong place! As if running 26.2 miles weren’t tough enough, here we spotlight the most challenging road (paved or unpaved) marathons in North America. With high altitude, brutal hills and extreme weather, these 12 races take perverse pleasure in extracting as much blood, sweat & tears as possible from their runners. Because for better or worse, on race day miserable is memorable.

Got a favorite grueling road marathon we missed? Don’t be shy—review it on RaceRaves and enlighten us in the Comments below!

Races that include distances other than the marathon are indicated by a *.


Heart of America Marathon logoHeart of America Marathon – Columbia, MO (Sep 4, 2017)
(marathon)
What’s the challenge? Unrelenting hills & warmer temps suck the life from your legs
 
It may or may not be coincidence that Heart of America takes place every year on Labor Day—but it’s certainly appropriate. With “sloping hills nearly the entire way” (@olsonm73) and race-day temperatures on the warmer side, HOA has been punishing novice and seasoned legs alike since 1960. So exhausted finishers will be thrilled to discover ice baths awaiting at the finish (how many races offer that?). HOA’s appreciative runners also rave about the event’s value, citing the no-frills, hometown ambiance and post-race pizza party. And for masochists who like to do things the hard way, the course is a USATF-certified Boston Qualifier. Whether it’s the scenic countryside route, the energetic support of top-notch volunteers or simply the aerobic challenge, Heart of America will keep your own ticker working overtime.

Rim Rock Run logoRim Rock Run* – Grand Junction, CO (Nov 4, 2017)
(marathon, marathon relay, half marathon)
What’s the challenge? A gradual 9-mile ascent to the course’s high point at 6,600ft

In a state that boasts 53 peaks of at least 14,000 feet plus a bevy of high-altitude trail races, the Rim Rock Run may at first blush seem like “Colorado Lite”. But don’t let its meager max elevation of 6,600 feet fool you; in order to reach the top, you’ll have to climb nearly one-third of those 6,600 feet in the race’s first nine miles. And since what goes up must come down, the second half of the winding course takes back all 2,000 feet of elevation gain and more, with a quad-pounding descent to the finish line in Fruita. Luckily all this pain doesn’t come without gain, as rewarding your efforts are spectacular, panoramic views of soaring red rock canyons and the towering sandstone formations of Colorado National Monument. You’ll even traverse three tunnels along the way. And while other Colorado races may literally take your breath away, none succeeds in the figurative sense more than Rim Rock.

Polar Bear Marathon logoPolar Bear Marathon* – Churchill, Manitoba, Canada (Nov 18, 2017)
(50K, marathon, half marathon)
What’s the challenge? Extreme cold & wind chill; potential polar bear sightings on the course

Known as the “Polar Bear Capital of the World,” the remote town of Churchill sits on the banks of the Hudson Bay at the northern tip of Manitoba. Factoring in wind chill, temperatures in late November routinely fall below -30°C (-22°F) with an average monthly snowfall of 40 cm (16 inches). Frostbite happens quickly in those conditions, demanding that runners dress in multiple protective layers with all exposed areas covered. If you think running 26.2 miles in a singlet and shorts is a struggle, try doing it in a parka and ski pants. Unlike other races that include “Polar Bear” in their name to signify a cold-weather activity, Churchill’s marathon is the real deal. And the race’s selling point is its namesake, i.e. the town’s autumn residents who migrate toward the bay in search of food. To guarantee runner safety and discourage curious polar bears and wolves, participants run in pairs accompanied by a support vehicle that doubles as a mobile aid station.
Registration limited to 40 runners.

Harpeth Hills Flying Monkey Marathon logoHarpeth Hills Flying Monkey Marathon – Nashville, TN (Nov 19, 2017)
(marathon)
What’s the challenge? Steep, unrelenting hills

It’s worth noting that Tennessee hosts not only the most difficult race in the nation (The Barkley Marathons) but also one of its most difficult road marathons. Staged entirely within Nashville’s densely wooded Percy Warner Park, the Harpeth Hills Flying Monkey is “meant to be an antidote” to fast and flat marathons. And while the organizers may take themselves lightly, they clearly take their responsibilities seriously with over 7,200 feet of total elevation change, grades of up to 12% and a cadre of dedicated volunteers providing encouragement and guidance along the way. With landmarks like “Three Mile Hill” and “Nine Mile Hill” that feature lung-burning ascents and quad-punishing descents, the HHFM isn’t monkeying around. Or maybe it is. In any case, your legs will doubtless be ready to See no hills, hear no hills, speak no hills long before reaching the finish.
Registration is a weighted lottery and opens for one week only (Aug 1–8) each year.

Let’s Go Haiti Marathon* – Port-au-Prince, Haiti (Feb 25, 2018)
(marathon, half marathon)
What’s the challenge? A “Choose Your Own Adventure”–style course in a third-world nation

Now in its fifth year, Let’s Go Haiti boasts one of the most honest slogans out there: “A race like no other in a country like no other.” But it’s not the stifling Caribbean heat or abundant hills that earn Haiti a spot on this list. Rather, with its insufficient signage, unpredictable water stops and living, breathing on-course obstacles (including pigs, goats and chickens), the race feels more like a children’s “Choose Your Own Adventure” book than a typical marathon. Indeed, despite receiving finisher medals none of the 17 marathon participants in 2017 ran the full 26.2-mile distance, and most received no official finish time. Nonetheless @Donnald69 calls the race “the greatest experience that I have ever had at a marathon.” Because the most challenging—and most rewarding—aspect of Let’s Go Haiti may just be the way it forces runners out of their comfort zone, allowing them to experience the raw, unfiltered vibrancy of a proud yet impoverished nation working to build a better future.

Foot Levelers Blue Ridge Marathon logoFoot Levelers Blue Ridge Marathon* – Roanoke, VA (Apr 21, 2018)
(double marathon, marathon, marathon relay, half marathon, 10K, family mile)
What’s the challenge? Significant hills, including four climbs & descents of 450+ feet each

Talk about putting your money where your mouth is: Blue Ridge race organizers are so confident in their claim to “America’s Toughest Road Marathon”, they trademarked the slogan. And with 7,430 feet of elevation change, they ain’t just whistlin’ Dixie. Starting in downtown Roanoke, the race winds through several local parks and culminates in a climb to the top of Roanoke Mountain (2,145 feet) in mile 7. Significant climbs at miles 13 and 19 follow, with plenty of rolling hills sprinkled in to keep the legs motivated. Once atop Roanoke Mountain, sweeping vistas are the payoff for a jog well run. Likewise, Blue Ridge Mountain scenery and flatter stretches along the Roanoke River help to offset mounting fatigue. And just before the midway point of the race stands the 88-foot-tall Roanoke Star, which at night watches over the city in a blaze of neon from its vantage point in Mill Mountain Park.

Whiskey Row Marathon logoWhiskey Row Marathon* – Prescott, AZ (May 5, 2018)
(marathon, half marathon, 10K, 2 miler)
What’s the challenge? High altitude + steep hills = tough love

“Are You Tough Enough?” the WRM logo asks prospective runners. It’s a fair question, since any course with an elevation profile that resembles a capital “M” clearly means business. And when that entire course is run above a mile in elevation, you know you’ve got your work cut out for you. Named for the historic stretch of saloons that recall Prescott’s Gold Rush roots, Whiskey Row wastes no time in bringing the pain. Starting on an immediate uphill trajectory, the out-and-back course covers five miles on asphalt before transitioning to a well-maintained dirt road for the next eight. Reaching its zenith (~7,000 feet) in mile 9, the course drops to 5,600 feet at the midway turnaround point before retracing its steps up and back down to Whiskey Row. By the time you cross the finish line in Courthouse Square, you may need a good stiff drink to take the edge off and help you savor the achievement of a hard-earned Personal Worst.

Wyoming Marathon Races logoWyoming Marathon Races* – Laramie, WY (May 28, 2017; 2018 TBD)
(50K, marathon, half marathon, 5K)
What’s the challenge? High altitude and long, challenging climbs

Few events deliver a natural runner’s high like the Wyoming Marathon Races. With a course that runs between 8,000 and 8,800 feet in elevation, Wyoming has an attitude for altitude. The good news is that the start line sits at just over 8,700 feet, the high point of the course. The bad news is, so does the finish line. The out-and-back course drops nearly 700 feet in the first five miles, though with an asterisk since you’ll be climbing those same hills on your way home. This course giveth and taketh away, as the dirt and gravel roads—77% of the course is unpaved—help to offset some of the pounding on your legs, if not your lungs. And for those hardy souls who fancy belt buckle bling, the race offers a 50K distance too. Don’t say you weren’t warned, though—after all, WMR’s slogan is “Where the race director promises you nothing, and he delivers.” Happy 40th birthday, Wyoming Marathon!

Skagway Marathon logoSkagway Marathon* – Skagway, AK (June 10, 2017; 2018 TBD)
(marathon, half marathon)
What’s the challenge? Frequent hills with extended climbs, including the “Hill of Endurance”

“ALASKA’S TOUGHEST MARATHON” screams the home page on the Skagway Marathon website. Two-time champ Quinn Webber agrees, calling the course “absolutely brutal” and “the 7th circle of Hell.” Skagway owes much of this hard-earned reputation to its frequent elevation changes. But what sets it apart from other difficult road marathons is the Hill of Endurance, a cruel 2-mile/470-foot climb up to (and back down from) the turnaround at the halfway point. The largely paved course mixes in gravel and dirt stretches featuring—if it’s any consolation to your uncooperative legs—some of the most pristine natural beauty found anywhere in the world. And the Hill of Endurance notwithstanding, the toughest part of the marathon may be getting to the start line, as the town’s geographic isolation means most of its one million annual tourists arrive by cruise ship.

Calico Racing's Running with the Devil logoRunning with the Devil* – Las Vegas, NV (June 23–24, 2018)
(100 miler, 50 miler, 50K, marathon, half marathon, 10K, 5K)
What’s the challenge? Extreme heat, with temperatures exceeding 100°F

Now’s your chance to break out the reflective, all-white running gear! As the name suggests, Running with the Devil is a celebration of insolation. Resurrected in 2016 after a three-year hiatus (including its 2013 cancellation due to concerns over excessive heat), RWTD returned with a paved course that promises “pure Mojave Desert running at its finest!” And with distance options that range from 5K to 100 miles, Calico Racing’s sun-drenched event feels like a training ground for Badwater wannabes. Frequent hydration breaks let runners stop and smell the Mountain Roses, plus other high desert vegetation including Joshua trees and Pinyon-Juniper woodlands. And for anyone looking for a silver lining in the cloudless Nevada skies: at a start line elevation of 4,500 feet, you and your overworked cooling systems can take comfort in the fact it’s a very dry heat.

Madison Marathon (Montana) logoMadison Marathon* ­– Madison, MT (July 21, 2018)
(marathon, marathon relay, half marathon)
What’s the challenge? Highest altitude on this list (8,300ft low, 9,500ft high), significant hills

The review headline from first-time marathoner @treyhorbins says it all: “Holy shit….” Madison’s claim to being the “highest road marathon on planet Earth” may be outdated (Ladakh in India is higher), but make no mistake: it’s high enough. At a starting elevation of 9,250 feet and two brutal climbs in the first 5 miles, you may wonder how Big Sky Country can be so stingy on oxygen. This is no big-city race, as reinforced by the long shuttle rides that transport runners to the remote start (like riding in a “big, orange maraca,” notes finisher Dan Solera). But the end justifies the means, with 26.2 miles of open-air freedom on dirt & gravel roads, featuring (literally) breathtaking views and potential wildlife encounters with bears, moose and antelope. Like the website says, “Long distance running just doesn’t get any better than this.”
     Not enough punishment? The Big Sky Marathon, offered the next day, provides a “double” opportunity for Marathon Maniacs, Half Fanatics and any masochist whose oxygen-deprived brain may be experiencing short-term Madison memory loss.

Crater Lake Rim Runs logoCrater Lake Rim Runs* – Crater Lake, OR (Aug 12, 2017; 2018 TBD)
(marathon, 13 miler, 6.7 miler)
What’s the challenge? High altitude, long climbs & descents

Formed thousands of years ago from the caldera of a collapsed volcano, Crater Lake is the deepest lake in the U.S. and a remarkable centerpiece for one of the nation’s toughest road marathons. The course wastes no time in setting expectations, with an immediate half-mile ascent starting at 7,500 feet of elevation. From there the pristine blues and greens of southern Oregon will take your breath away, assuming you have any left once the undulating course has its way with you. But the organizers save arguably the worst for last. At mile 22, runners pass by the finish line and continue on a steep two-mile climb up a road composed of dirt & pumice cinders, before retracing their steps back to the finish. By this final downhill, the unforgiving combination of altitude and hills will leave most runners’ legs ready to crater.
     On a related note, the Lake Tahoe Marathon features a similarly strenuous combination of altitude, hills & brilliant blues all centered around the country’s second-deepest lake. (Thanks to Dave Munger, whose Crater Lake blog post we referenced)

  1. If you think Heart of America in Missouri on Labor Day is tough, you should sample the heat and humidity of Mississippi by running the Tupelo Marathon, which is always the Sunday of Labor Day weekend. Talk about some brutal conditions! The race starts at 5 a.m. to try to get ahead of the heat, but it doesn’t really help much. The year I ran it (2012) I arrived at the start area at 4:30 a.m. and it was already 77 degrees and 97% humidity. It only got worse when the sun came up. The race motto is, “Trample the Weak, Hurdle the Dead.” Another stupidly hot race (and very hilly, too) is the Blister in the Sun Marathon held each August in Cookeville, TN ( I think the race director is affiliated with the Harpeth Hills race, too). Five loops of 5 miles and change each means you get to climb every hill (and there are several of them) five times!

Your turn – what do you think?
