The Aspen Backcountry Marathon is one of Colorado’s most stunning trail races, utilizing the world-class trail network that surrounds the legendary resort town of Aspen. All three distances \u2014 the 50K, marathon, and heavy half-marathon \u2014 run almost exclusively on single-track dirt trails with diverse terrain: challenging climbs through aspen groves, high ridge traverses with panoramic views of the Elk Mountains, and technical descents back into the valley. The 50K distance includes an out-and-back to the McNamara Hut, part of Colorado’s storied 10th Mountain Division Hut System. The start and finish at Rio Grande Park places runners in the heart of Aspen.<\/p>\n
The 2026 race takes place on Saturday, August 1, with the 50K starting at 6:00 AM (civil twilight), the marathon at 7:30 AM, and the heavy half at 8:00 AM. The overall elevation gain for each distance challenges even experienced trail runners. Post-race, Rio Grande Park transforms into a festival with live music all day, food trucks, a silent auction, beer, and youth group activities \u2014 all coinciding with the Rotary Club’s Duck Derby fundraiser on the Roaring Fork River at 1:30 PM.<\/p>\n
Few American mountain towns offer trail access as extraordinary as Aspen, and the Backcountry Marathon lets runners experience the best of it in a single event. The combination of world-class trails, Elk Mountain scenery, the community festival atmosphere at the finish, and Aravaipa Running’s reputation for top-tier race production makes this one of the most desirable trail race entries in Colorado. The heavy half option makes the experience accessible to runners who want the Aspen experience without the marathon commitment.<\/p>\n
Aspen sits at 7,908 feet with trails climbing well above 11,000 feet \u2014 plan to arrive at least 2\u20133 days early from sea level. August in the Rockies means afternoon thunderstorms are nearly guaranteed; the morning start is designed to keep runners on exposed ridges before storms develop, but carry a rain shell. The race sells out, so register promptly when registration opens in winter\/spring via Aravaipa Running.<\/p>\n

Sierre-Zinal is an iconic 31 km mountain race in the Swiss Alps, famously known as the ‘Race of the Five 4,000s’ for its views of five legendary peaks. It attracts elite athletes and amateurs alike for its challenging elevation and breathtaking scenery.<\/p>\n Known as the “Race of the Five 4,000s,” Sierre-Zinal offers some of the most spectacular views in the trail running world. The point-to-point course stretches 31 kilometers through the heart of the Swiss Valais Alps, connecting the town of Sierre to the mountain village of Zinal. Along the way, runners are treated to panoramic views of five legendary 4,000-meter peaks: the Weisshorn, Zinalrothorn, Obergabelhorn, Matterhorn, and Dent Blanche. The route is famous for its initial, punishing climb from Sierre, followed by a fast, scenic traverse across high-altitude alpine meadows and a technical descent into Zinal. Landmarks like the Hotel Weisshorn provide iconic cheering points for spectators and historic markers for participants.<\/p>\n The Sierre-Zinal race is a test of both climbing prowess and raw speed, featuring 2,200 meters of elevation gain and 1,100 meters of descent. The event is uniquely structured into two main categories: the “Tourist” category and the “Runner” category. The Tourist category, designed for amateur enthusiasts, starts early in the morning (between 04:45 and 06:15), allowing participants to experience the sunrise over the Alps. The “Runner” category, which includes elite athletes and those aiming for competitive times, starts later at 11:00. In addition to the main 31 km event, the “Junior” race offers a 19 km course starting from Chandolin, while younger children can participate in the “Course des Cinq Obstacles” in Sierre. The 53rd edition is scheduled for Saturday, August 8, 2026.<\/p>\n Sierre-Zinal is widely regarded as one of the most prestigious mountain races in the world, often cited as a must-do event for any serious trail runner. Its reputation stems from a perfect blend of challenging terrain, world-class competition, and a deep sense of tradition that has been cultivated since its inception in 1974. Runners love the inclusive atmosphere that welcomes both elite professionals and passionate amateurs on the same day. The course is remarkably runnable for a mountain race, allowing for blistering speeds that have seen legends like Kilian Jornet set incredible records. The local support is unmatched, with the entire Val d’Anniviers community coming together to create a festive, welcoming environment for participants from over 60 nationalities.<\/p>\n Experience the magic of the Swiss Alps by registering for the next edition.

Aspen Trail Marathon","description":" Haulin Aspen Trail Marathon & Half Marathon runs through the spectacular trail network surrounding Sunriver Resort and the Deschutes National Forest in Central Oregon. The course winds through golden aspen groves (at their most spectacular in late summer), old-growth ponderosa pine forests, and open meadows with sweeping views of the Three Sisters, Mount Bachelor, and Broken Top. The marathon and half marathon share the same scenic forest terrain, making this one of Central Oregon’s premier late-summer trail experiences.<\/p>\n The 22nd Annual Haulin Aspen takes place Saturday, August 8, 2026, based near Sunriver, Oregon. Registration is through RunSignup. The course is a well-marked, well-supported trail race with aid stations staffed by enthusiastic volunteers. The modest field size (500-1,000 participants) gives the race an intimate feel that larger events can’t match. Sunriver Resort area provides excellent post-race accommodation and dining.<\/p>\n Haulin Aspen is a beloved fixture in the Central Oregon racing calendar precisely because it combines challenging, beautiful trails with a welcoming community atmosphere. The aspen groves in August light are genuinely stunning \u2014 photographers as well as runners make the trip. At 4,200 feet elevation, temperatures are cooler than Portland or Eugene in August, making for ideal trail running conditions. The Sunriver area’s resort amenities make it easy to reward yourself generously after the race.<\/p>\n Trail shoes with good traction are essential for the forest floor and aspen grove terrain. At 4,200 feet, sea-level runners should pace conservatively. Book Sunriver Resort or nearby Bend accommodation early \u2014 August weekends in Central Oregon are popular. The race fills to capacity; register as soon as registration opens.<\/p>\n Run through Oregon’s aspen gold \u2014 register at

200","description":" The Bigfoot 200 is a premier 200-mile point-to-point ultramarathon that traverses the technical and volcanic terrain of Washington’s Cascade Mountains.<\/p>\n The Bigfoot 200 Endurance Run offers an unparalleled journey through the rugged and diverse landscapes of the Cascade Mountains in Washington State. The race begins at the base of the iconic Mount St. Helens, where runners navigate through the otherworldly “blast zone” and vast lava fields created by the 1980 eruption. This section provides stark, moon-like scenery with breathtaking views of the crater. As the course progresses, participants plunge into deep, lush old-growth forests, where massive Douglas firs and moss-covered trails provide a complete contrast to the volcanic terrain. The route also takes runners past the base of Mount Adams and offers sweeping vistas of Mount Rainier and Mount Hood on clear days. The journey is defined by technical single-track trails, steep ridgelines, and numerous stream crossings that challenge even the most experienced ultramarathoners.<\/p>\n As the first point-to-point 200-mile race in the United States, the Bigfoot 200 is a non-stop endurance event covering approximately 207.9 miles. The course is exceptionally demanding, featuring an estimated 45,563 feet of elevation gain and 46,880 feet of elevation loss. Runners have a total of 107 hours to complete the distance, making it a test of both physical strength and mental resilience. The race starts at Marble Mountain Sno-Park near Cougar, WA, and concludes at White Pass High School in Randle, WA. Along the way, participants are supported by 12 full aid stations, five of which serve as designated sleep stations where runners can rest and recharge. Due to the remote nature of the course, mandatory gear is strictly enforced, and runners are encouraged to utilize a crew and pacers to navigate the long stretches between checkpoints.<\/p>\n Runners are drawn to the Bigfoot 200 for its reputation as one of the most scenic and difficult ultramarathons in the world. It is part of the prestigious “Triple Crown of 200s,” alongside the Tahoe 200 and Moab 240. The sense of community is profound; because the race spans several days, runners often form deep bonds with fellow participants, volunteers, and the organizers at Destination Trail. The race provides a “graduate level” experience that goes beyond a standard marathon, offering a life-changing exploration of the self and the wild. Many athletes describe the finish at White Pass High School as a transcendental moment, celebrating the culmination of a journey that tests every facet of their being. The historic significance of running through the Mount St. Helens National Volcanic Monument adds a layer of awe and respect for the natural power of the region.<\/p>\n Visit the official race website

Trail 100 Run","description":" The Leadville Trail 100 Run \u2014 the Race Across the Sky \u2014 is the defining event of American ultrarunning. The 99.7-mile out-and-back course starts and finishes in Leadville, Colorado (10,152 feet, the highest incorporated city in the United States) and crosses the legendary Hope Pass twice at 12,500\u201312,600 feet, climbs the rugged Powerline section, traverses technical stretches of the Colorado Trail, and descends to the lowest point of 9,200 feet at Twin Lakes. The course accumulates 15,492 feet of elevation gain across its full length, with 11 aid stations to sustain runners through the mountains.<\/p>\n The 2026 race starts August 22 at 4:00 AM from the corner of 6th and Harrison in Leadville. The starting line opens at 3:00 AM. Pacers are allowed after mile 61.8 (Twin Lakes inbound). The official 30-hour cutoff earns finishers the coveted small silver belt buckle; completing the course in under 25 hours earns the Big Buckle \u2014 a trophy that defines careers. Minimum age is 18 on race day. The race is managed by the Leadville Race Series and typically sells out within minutes of registration opening.<\/p>\n The Leadville 100 launched the modern ultrarunning movement when it was founded in 1983, and it remains the aspirational pinnacle for hundreds of thousands of runners worldwide. The combination of extreme altitude, rugged terrain, remote mountain wilderness, and the simple binary outcome \u2014 finish or DNF \u2014 gives the race a gravity and mystique unmatched in American endurance sports. The Hope Pass double-crossing in the dark of night is one of the most profound experiences available in trail running.<\/p>\n Training at altitude is almost impossible to replace with sea-level preparation. If you live below 5,000 feet, plan to arrive in Leadville at minimum one week before race day \u2014 preferably two. The average pace needed just to finish (30 hours) is approximately 18 min\/mile including all stops, which sounds easy until you’re above 12,000 feet at mile 50 after midnight. Crew and pacers are essential, and a meticulously prepared drop bag system across the 11 aid stations is the difference between finishing and not.<\/p>\n Registration opens in January via the Leadville Race Series at leadvilleraceseries.com<\/a>. Spots sell out in minutes \u2014 set a calendar reminder and have your payment information ready before registration

Trail 100","description":" The Leadville Trail 100 Run is a legendary 100-mile ultramarathon through the Rocky Mountains, known for its extreme elevation and “Grit, Guts, and Determination” ethos.<\/strong><\/p>\n The “Race Across the Sky” follows a brutal out-and-back course through the heart of the Colorado Rockies, featuring over 15,000 feet of elevation gain. Runners start at 10,200 feet in Leadville and face grueling climbs over Sugarloaf Pass and the notorious Powerline section. The true crux of the course is the double ascent of Hope Pass, which peaks at 12,600 feet, challenging participants with thin air and technical terrain. The route includes a mix of forest trails and mountain roads, leading to the turnaround point at the ghost town of Winfield before returning to the iconic finish line on Harrison Avenue.<\/p>\n The Leadville 100 is one of the most prestigious and oldest 100-mile races in the United States, forming a key part of the Grand Slam of Ultrarunning. Its origins as a community-saving effort give it a unique atmosphere where “family” and “legendary” are common themes. Runners compete not just for the finish, but for the coveted silver or gold belt buckles\u2014with the “Big Buckle” awarded for finishing under 25 hours. The prestige of the race attracts world-class athletes, yet it maintains a deeply inclusive spirit, honoring the local mining heritage and the legendary Tarahumara runners who famously dominated the race in the 1990s.<\/p>\n Arrive in Leadville at least a week early to acclimate to the extreme altitude, as the entire course sits above 9,200 feet. The free Race Across the Sky Expo in downtown Leadville is a must-visit for packet pickup and gear. Be prepared for volatile weather; even in August, conditions can shift rapidly from 70-degree sunshine to freezing rain, hail, or snow. Utilize the official shuttle system for crew and spectators, as parking in town and at aid stations like Twin Lakes is extremely limited.<\/p>\n The Leadville Trail 100 was founded in 1983 by Ken Chlouber and Merilee Maupin to revitalize the town’s economy after the closure of the Climax Molybdenum Mine. What began with 45 runners has grown into a world-class event that supports the community through the Leadville Trail 100 Legacy Foundation. This nonprofit provides $2,000 scholarships to every local high school graduate pursuing higher education and funds various community grants to ensure Leadville remains a thriving place to live and work.<\/p>\n Register at the official race

Mountain Run","description":" The Telluride Mountain Run is one of the most visually spectacular mountain running events in the American West, set above the jaw-dropping box canyon town of Telluride in the heart of Colorado’s San Juan Mountains. Runners navigate old mining roads, technical singletrack, and sweeping alpine tundra over mountain passes and exposed ridgelines, with portions of the course reaching above 13,000 feet. The 65-mile distance \u2014 new for 2026 \u2014 starts at 6:00 AM from Telluride Town Park and traverses some of the most dramatic high-altitude terrain available to any ultrarunner in North America.<\/p>\n The 2026 Telluride Mountain Run takes place August 22\u201323. The 65-mile ultra starts Saturday, August 22, at 6:00 AM from Telluride Town Park with a mandatory safety meeting at 5:00 PM the evening before (Friday, August 21). The race is produced by Highline Running Adventures and registration opens February 1, 2026. Multiple distances are offered across the race weekend. The focus of every Telluride Mountain Run distance is the experience: the burn of high elevation, the striking colors of the San Juans, and the profound satisfaction of finishing in one of Colorado’s most beautiful towns.<\/p>\n Telluride is widely regarded as the most beautiful mountain town in Colorado, and the Mountain Run gives athletes the opportunity to experience its backcountry on foot. The combination of extreme altitude, technical terrain, historic mining road character, and the backdrop of the San Juan Mountains \u2014 including peaks like Wilson, El Diente, and the Wilsons \u2014 creates a once-in-a-lifetime running experience. The post-race celebration in Telluride’s Main Street is a worthy reward for any finisher.<\/p>\n Telluride sits at 8,750 feet with race terrain climbing to 13,000+ feet. For the 65-mile distance especially, arriving a week early for acclimatization is critical. August mountain weather in the San Juans is notoriously changeable \u2014 afternoon lightning storms are near-daily occurrences, and the high route segments have zero shelter. Carry mandatory emergency gear and familiarize yourself with the course cutoff requirements. Trail shoes with aggressive traction and rock plates are essential for the technical upper sections.<\/p>\nCourse Highlights<\/h3>\n
