SUMMARY:Aspen Backcountry Marathon
DESCRIPTION:Course Highlights\nThe 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 — the 50K\, marathon\, and heavy half-marathon — 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. \nRace Details\nThe 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 — all coinciding with the Rotary Club’s Duck Derby fundraiser on the Roaring Fork River at 1:30 PM. \nWhy Runners Love It\nFew 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. \nRace Weekend Tips\nAspen sits at 7\,908 feet with trails climbing well above 11\,000 feet — plan to arrive at least 2–3 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. \nRegister\nRegistration opens in early winter at aravaiparunning.com. Aravaipa events are popular and fill quickly — sign up for the waitlist notification email.

SUMMARY:Sierre-Zinal
DESCRIPTION: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. \nCourse Highlights\nKnown 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.

SUMMARY:Haulin Aspen Trail Marathon
DESCRIPTION:Course Highlights\nHaulin 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. \nRace Details\nThe 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. \nWhy Runners Love It\nHaulin 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 — 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. \nRace-Weekend Tips\nTrail 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 — August weekends in Central Oregon are popular. The race fills to capacity; register as soon as registration opens. \nRun through Oregon’s aspen gold — register at RunSignup.

SUMMARY:Bigfoot 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. \nCourse Highlights\nThe 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. \nRace Details\nAs 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. \nWhy Runners Love It\nRunners 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. \nAt a Glance\n\nLocation: Cougar\, WA — United States\nNext Date: 2026-08-14\nDistances: 207.9 miles\, 20 miles\nStart Time: 12:00\n\nRegister & Learn More\nVisit the official race website for entry details\, course maps\, and registration: https://www.destinationtrailrun.com/bigfoot

SUMMARY:Bridger Ridge Run
DESCRIPTION:Have you always been up for a running challenge? How about a marathon with a breathtaking view and steep climb? Well\, you’re just in luck. Bridger Ridge Run is a fun and competitive race that’s worth every penny spent and every sweat bead shed. With Rocky Mountain peaks and steep ridges\, the Bridger Ridge Run trail has been ranked as one of the most technical running trails in America. It’s a grueling test of physical ability\, endurance\, and mental toughness that truly showcases the beauty of Montana’s rugged terrain. \n1. The Trail: \nBridger Ridge Run is a 20-mile trail that stretches from Fairy Lake to the M Trailhead. The trail climbs about 6\,900 feet to a towering height of 8\,700 feet above sea level at the highest point of the Bridger Mountains. The course is marked with orange ribbons and flags\, but runners are expected to be familiar with the trail. Due to the technical nature of the terrain\, runners should be skilled at both uphill and downhill running. \n2. Training:\nTraining for Bridger Ridge Run requires a great level of commitment and consistency. The trail is unrelenting\, and only the most seasoned endurance athletes can complete it. To prepare adequately\, include hill workouts\, trail running\, and long-distance running in your training routine. Be sure to work on your balance and ankle strength as you navigate the steep and slippery ascents and descents. \n3. Weather:\nAs you prepare for the race\, it’s essential to be aware of the weather conditions. Montana’s weather can be unpredictable\, and it’s recommended that you pack extra layers in case the weather changes unexpectedly. The Bridger Ridge can be windy\, cold\, and wet\, with lightning being a common occurrence. It’s essential to monitor the weather forecast and prepare for everything. \n4. Hydration and Nutrition:\nStaying hydrated and nourished is key to your success on the trail. You’ll need to carry adequate water\, and many runners bring a hydration pack to ensure easy access to it. Since Bridger Ridge Run is challenging\, runners need to replenish regularly with salty and carbohydrates-rich food.

SUMMARY:Leadville Trail 100 Run
DESCRIPTION:The Leadville Trail 100 Run is a legendary 100-mile out-and-back ultramarathon through the high-altitude terrain of the Colorado Rockies\, famously known as the “Race Across the Sky.” \nCourse Highlights\nThe Leadville Trail 100 Run course is a brutal out-and-back ultramarathon that will push even the toughest runners to their limits. Starting and finishing in the heart of Leadville at 10\,200 feet\, the course traverses the rugged and unrelenting terrain of the Colorado Rockies. Key highlights include the steep and punishing climbs of Powerline\, the high-altitude challenges of Sugarloaf Pass\, and the technical sections along the scenic Colorado Trail. The defining feature of the race is Hope Pass\, which reaches a staggering peak elevation of 12\,500 feet. Runners must summit this pass twice—once outbound and once inbound—gasping for breath in the thin mountain air while taking in some of the most stunning vistas in the country. With over 15\,000 feet of total elevation gain\, the course is a true test of physical and mental endurance. \nRace Details\nKnown as the “Race Across the Sky\,” the Leadville Trail 100 Run is one of the oldest and most storied endurance running events in the world. The race begins at 04:00 on Harrison Avenue and has a strict 30-hour time limit for completion. Success is marked by the attainment of the coveted belt buckles: the “Big Buckle” for those finishing under 25 hours and the “Small Buckle” for those who cross the line within the 30-hour cutoff. The event is part of the Leadville Race Series and typically takes place in late August. Participants are supported by a network of aid stations\, including key points at Mayqueen\, Outward Bound\, Twin Lakes\, and the Winfield turnaround. Due to its extreme nature\, the race requires significant preparation\, and entries are typically allocated through a lottery system or by qualifying at other Leadville Race Series events. \nWhy Runners Love It\nThe Leadville Trail 100 Run is more than just a race; it is a pilgrimage for the ultrarunning community. Founded in 1983 by local miner Ken Chlouber to revitalize the town of Leadville after the closure of the Climax Mine\, the event is steeped in history and local pride. Runners are drawn to the race by the mantra of “Grit\, Guts and Determination” and the legendary red carpet finish that awaits every finisher. The community support in Leadville is unparalleled\, with residents and volunteers creating an atmosphere of encouragement that helps athletes through their darkest miles. The race’s legacy of charitable impact through the Leadville Trail 100 Legacy Foundation further enhances its prestige\, making it a bucket-list event for athletes who seek to etch their names among the “Leadville Legendary.” \nAt a Glance\n\nLocation: Leadville\, CO — United States\nNext Date: 2026-08-22\nDistances: 100 miles\nStart Time: 04:00\n\nRegister & Learn More\nVisit the official race website for entry details\, course maps\, and registration: https://www.leadvilleraceseries.com/run/leadvilletrail100run/

SUMMARY:Leadville Trail 100 Run
DESCRIPTION:Course Highlights\nThe Leadville Trail 100 Run — the Race Across the Sky — 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\,500–12\,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. \nRace Details\nThe 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 — 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. \nWhy Runners Love It\nThe 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 — finish or DNF — 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. \nRace Weekend Tips\nTraining 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 — 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. \nRegister\nRegistration opens in January via the Leadville Race Series at leadvilleraceseries.com. Spots sell out in minutes — set a calendar reminder and have your payment information ready before registration opens.

SUMMARY:Telluride Mountain Run
DESCRIPTION:Course Highlights\nThe 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 — new for 2026 — 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. \nRace Details\nThe 2026 Telluride Mountain Run takes place August 22–23. 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. \nWhy Runners Love It\nTelluride 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 — including peaks like Wilson\, El Diente\, and the Wilsons — creates a once-in-a-lifetime running experience. The post-race celebration in Telluride’s Main Street is a worthy reward for any finisher. \nRace Weekend Tips\nTelluride 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 — 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. \nRegister\nRegistration opens February 1\, 2026 at runtelluride.com. Pre-registration is available for the 65-mile distance. With limited entries and strong demand\, register promptly on opening day.
