For years, the 100-mile distance reigned as trail ultrarunning’s defining test—the point where endurance, ambition, and identity converged at the sport’s outer edge. It was the standard that shaped legends and set the tone for what it meant to fully commit. But that long-standing benchmark is beginning to give way. Across the U.S., a growing number of runners are pushing beyond it, gravitating toward races of 200 miles or more that require not just a single day of effort, but sustained movement across multiple days and nights.

What once felt like a niche experiment has rapidly entered the mainstream. Over the past decade, 200-plus-mile races have multiplied, with new events emerging nationwide and participation steadily increasing. (The category grew 114 percent year-over-year in 2024-2025, according to the American Trail Running Association.) Early standouts like Tahoe 200 and Bigfoot 200 helped establish the format, while newer events such as Cocodona 250—and even longer 300-mile events like the Arizona Monster 300 and Viper 300—have accelerated its momentum.

Here’s a listing of 200-mile+ races in the U.S. in 2026-2027.

Pigtails Challenge

May 23-24, Renton, Washington

The Pigtails Challenge is a multi-distance ultrarunning event, offering races from 50K up to 200 miles on a looped course within the Lake Youngs Watershed. The route is primarily non-technical, featuring groomed dirt and gravel trails with a rolling profile that gains roughly 900 feet per loop, which adds up quickly over longer distances. Runners tackle repeated laps of 9.4 miles, creating a format that’s straightforward logistically but mentally taxing, with the option to stop never far away.

Known for its welcoming atmosphere and runnable terrain, the race appeals to both first-time ultrarunners and seasoned athletes seeking a long-distance challenge without highly technical trails. The event typically draws between 100 and 500 participants across all distances, striking a balance between a lively turnout and a close-knit, community feel.

Infinitus

May 21-30, Ripton, Vermont

The Infinitus event in Ripton, Vermont, is a multi-day trail ultrarunning festival held at Silver Towers Camp in the heart of the Green Mountain National Forest, known for its extreme distances and rugged, grassroots vibe. The event features a wide range of race options, from a 9-mile run and marathon to 88K, 100-mile, and 250-mile races, along with multi-day “Penta” and “Deca” marathon challenges and the signature 888K (551-mile) event—one of the longest trail races in the U.S.

The course follows a figure-eight (infinity-shaped) design made up of two loops: a shorter loop of roughly 8.5 to 9 miles with about 2,000 feet of climbing, and a longer loop of approximately 17 to 18 miles with more than 2,500 feet of elevation gain. Depending on the distance, runners alternate between these loops, repeatedly returning to a central camp that simplifies logistics while intensifying the physical and mental demands.

The terrain reflects classic New England trail conditions, with rugged singletrack, forest roads, and snowmobile trails covered in rocks, roots, mud, and occasional stream crossings. Steep ascents, technical footing, and relentless elevation gain combine to create a true backcountry challenge that rewards durability, pacing, and problem-solving over multiple days.

More than just a race, Infinitus is defined by its strong community spirit and immersive camp environment, where runners eat, rest, and share the experience together while pursuing distances that stretch far beyond traditional ultramarathon limits.

Tahoe 200 Endurance Run

June 12-16, Lake Tahoe, California

The Tahoe 200 Endurance Run is one of the pioneering modern 200-mile ultramarathons in the U.S., launched by race director Candice Burt in the mid-2010s as part of a movement that pushed the boundaries of trail running. It quickly established itself as a flagship event in the 200-mile category, built around the concept of multi-day, single-stage racing that requires runners to carefully manage sleep, pacing, and recovery over several days.

The course spans roughly 200 miles—typically around 200 to 201 miles depending on the route—circling Lake Tahoe, the largest alpine lake in North America. Much of the route follows the Tahoe Rim Trail, traversing high-altitude terrain with approximately 35,000 to 36,000 feet of elevation gain across ridgelines, forests, and exposed alpine sections with expansive lake views.

Thanks to its prestige and limited field size, the race is known to sell out rapidly—often within hours of registration opening—as runners vie for a spot in one of the most coveted multi-day ultras in the world. Participation is generally capped at just a few hundred runners, adding to the event’s exclusivity.

More than just a long-distance race, the Tahoe 200 is defined by its scale and immersive nature, challenging runners to circle an entire mountain lake over three to four days while navigating rugged terrain, altitude, and the demands of self-management in one of ultrarunning’s most iconic events.

The Summit 200

July 27-Aug. 2, Frisco, Colorado

The Summit 200 is a high-altitude, 200-mile ultramarathon based in Frisco, Colorado, featuring a single-loop course that circles Summit County on a mix of singletrack trails, forest roads, and sections of paved recreation path. The course is defined by its relentless elevation profile—starting above 9,000 feet, climbing to nearly 12,800 feet, and totaling around 40,000 feet of vertical gain—making it one of the most physically demanding 200-milers in the country.

The field is intentionally kept small, typically limited to about 75 to 100 runners, giving the event a more intimate and understated feel despite the scale of the challenge. Though it has faced some early growing pains, the Summit 200 has quickly built a reputation for its rugged terrain, high-altitude difficulty, and bold design, establishing itself as a distinctive and formidable test in the evolving landscape of 200-mile ultrarunning.

Bigfoot 200 Endurance Run

Aug. 14-18, Mount St. Helens, Washington

The Bigfoot 200 Endurance Run is one of the pioneering modern 200-mile ultramarathons in the U.S., first held in 2015 and widely regarded as the first point-to-point race of its kind—helping spark the growth of the 200-mile movement. Created by the Destination Trail team, it quickly became a defining event, pushing runners into the realm of multi-day racing that requires careful sleep management, pacing, and self-sufficiency over four or more days.

The course covers roughly 200 to 208 miles through Washington’s Cascade Mountains, starting near Mount St. Helens and finishing in Randle, with more than 43,000 to 45,000 feet of elevation gain. Along the way, runners traverse a dramatic mix of terrain, including volcanic blast zones, lava fields, alpine ridgelines, old-growth forests, river crossings, and long, remote stretches of singletrack, with only minimal road sections near the end.

Widely considered one of the most difficult 200-milers in the U.S., Bigfoot combines relentless climbing, technical footing, and deep wilderness isolation with unpredictable mountain weather and the cumulative toll of multi-day fatigue. The route includes massive climbs—some exceeding 5,000 feet at a time—and long sections between aid, demanding both physical durability and strong mental resilience.

What sets the race apart is its immersive, expedition-like feel: runners move through the stark Mount St. Helens blast zone early in the race, later crest high ridgelines with views of Mount Rainier, and rely on a network of remote aid and sleep stations spread across the course. This blend of volcanic landscapes, dense forests, and sheer scale has made the Bigfoot 200 one of the most iconic—and unforgiving—ultramarathons in the world.

Old Ephraim 200

Aug. 24, Logan Utah

The Old Ephraim 200 is a demanding, point-to-point ultramarathon in northern Utah that spans roughly 215 miles through the remote Bear River Range, with about 40,000 feet of elevation gain across primarily singletrack trails and forest roads.

Aimed at seasoned ultrarunners, the race prioritizes true wilderness immersion, winding through dense pine and aspen forests, open meadows, and long, isolated stretches with very little pavement. The event takes its name from Old Ephraim, a legendary grizzly bear that once roamed the region in the early 1900s and became a lasting symbol of resilience and strength in local lore.

That history is deeply embedded in the race, with the course passing through areas tied to the bear’s story and even including an aid station at his gravesite, connecting modern endurance efforts with the enduring spirit of the mountains.
