Starting and finishing at Baldface Farm in Chatham, New Hampshire’s Evans Notch, the Baldface Scramble is a mountain trail race built around steep ledges, panoramic views, and single-track running. About 95 percent of the course is on unpaved trails, giving the event a distinctly rugged character rather than the feel of a road race with a short off-road section. Runners can choose between two course formats. The 14K follows the first loop over the Baldfaces before returning to the farm field. The 29K uses two different loops: after completing the Baldface section and reaching a fully stocked aid station back in the field, long-course runners head out again to climb over Mount Meader. Both routes ultimately descend from the mountains and return to the large finish field, where a post-race party awaits. The combination of steep ledges, broad mountain views, and substantial single track should appeal most to trail runners who enjoy demanding, scenic terrain and a course with a strong mountain personality. The loop structure also gives the longer race a clear transition point before its second major mountain section. The event is part of the White Mountain Endurance series and was first held in 2024.

Starting and finishing at Button Farm Living History Center in Germantown, this trail race explores the well-maintained paths of Schaeffer Farms. The course mixes flowing, twisty single-track with open farm-field running, stream crossings, log ramps, and several hills. Rocky and root-covered sections add a moderately technical character, giving runners a combination of speed, rhythm changes, and careful foot placement rather than a simple run on smooth paths. The setting should appeal to trail runners who enjoy varied terrain without requiring an extreme mountain environment. Faster athletes can make use of the flowing sections, while runners seeking a challenge will find interest in the creek crossings, uneven surfaces, and short climbs. Both courses begin and end at the living history center off Black Rock Road. EX2 Adventures produces the event with volunteer support, aid stations, medical support, music, race photography, awards, giveaways, and post-race food. The event also supports awareness and fundraising for two Montgomery County nonprofit organizations: Interfaith Works and Button Farm Living History Center. This combination of lively race operations, accessible woodland trails, farm scenery, and moderately technical footing makes the Schaeffer Farms stop a distinctive part of the Blue Crab Bolt trail-running series.

Starting and finishing at the Daylodge area of Alyeska Resort, this is a compact but serious mountain race that takes runners almost directly from near sea level into exposed alpine terrain. The opening follows Tanaka Cat Service Road before entering the Silvertip singletrack mountain-bike trail. From there, competitors confront the very steep Center Ridge, scrambling upward through Teacup Bowl toward the Headwall at about 3,800 feet. The high ridge rewards the climb with views across the Chugach Mountains, Turnagain Arm, hanging glaciers, and distant peaks. Its rolling bursts then lead toward the MAX’s weather station, where the character of the course changes sharply. Runners descend over loose rock and mountain heather before dropping into the heavily wooded Max’s Mountain trail. Hemlock and spruce, moss-covered fallen trees, and loamy ground create a markedly different setting below the exposed upper mountain. The descent is exceptionally steep and technical. Competitors may need to use nearby trees, while organizers install hand lines where necessary for balance and agility. Careful footwork is essential because the alpine sections carry rockfall hazards, and the route includes a strict cutoff before Center Ridge. Every entrant is required to inspect the full course before race day. This event best suits mountain runners comfortable with steep climbing, exposure, scrambling, loose footing, and demanding descents. The manageable overall length may also appeal to athletes seeking a concentrated alpine challenge rather than an ultra-distance effort. Cirque Series welcomes everyone from first-timers to elite competitors, but Alyeska’s technical terrain makes preparation, sound judgment, and confidence on rugged mountain trails especially important.

Starting and finishing in Creede, a historic Colorado mining town, this mountain ultra heads into the high country of the San Juan Mountains on a course that is 95 percent unpaved. Runners move between dirt and jeep roads, rocky singletrack, forest, open parks, stream crossings, and broad alpine tundra. The 100-mile route climbs as high as 13,261 feet and spends an extended stretch around Snow Mesa and the Continental Divide before descending toward the headwaters of the Rio Grande River and returning to town by a different route. The organizers deliberately embrace an old-school approach to trail running. Mileage is approximate rather than watch-perfect, and participants are expected to understand the route in advance, carry suitable clothing, water, and food, and remain reasonably self-sufficient. Although the course is marked, flags and ribbons can be disturbed by wildlife, making attention and route awareness part of the experience. Aid stations support the journey, but the event retains the character of an independent backcountry undertaking rather than a precisely measured road race. This is rugged, high-elevation terrain where conditions can change quickly. The official information warns runners to prepare for cold nights, exposed sections, rocky ground, mud, streams, lightning, and encounters with animals including elk, moose, cattle, bears, and mountain lions. Shared trails remain open to hikers, cyclists, motorized users, and horseback riders. The race will appeal most to experienced trail and ultra runners who enjoy sustained altitude, remote mountain scenery, and a course that rewards judgment as much as speed. The organizers nevertheless welcome anyone ready to challenge themselves, while emphasizing that outdoor experience and self-sufficiency are important for taking on either course.

Set on the edge of San Pablo Bay, this timed trail event uses a repeating loop through Point Pinole Regional Shoreline. Approximately 98 percent of the main loop follows dirt fire trails, taking runners along the shoreline for broad views of several bridges and surrounding mountains before returning through fragrant eucalyptus groves. The setting gives the race a distinctive mix of open waterfront scenery and shaded woodland rather than the point-to-point progression of a conventional trail race. Participants can compete individually or as teams of two or three. Team members may take turns in any order to build a combined total, while solo runners decide for themselves how steadily they want to keep moving. Completing a single loop is enough to be recognized as a finisher, so the format can serve very different goals: testing endurance, pursuing a personal distance target in a supported environment, or simply spending an active day on the trails. Walking and hiking are explicitly welcome, and the organizer notes that few entrants are expected to run continuously; rest periods and walk breaks are part of the experience. The repeated-loop design should appeal to runners who value regular access to support and the freedom to adjust their effort as the event unfolds. It is approachable for walkers and runners exploring timed events, yet it also offers experienced endurance athletes a controlled setting in which to see how far they can travel. An all-day picnic adds a social, race-party atmosphere, making the event as much about sharing the park with fellow participants as chasing a result.

Elder Creek Night Runs unfolds on Cahuilla Road near Anza in Southern California, carrying runners from a desert sunset into a night beneath the stars. Held with permission from the Cahuilla Band of Indians, the event uses a repeating trail loop surrounded by red shank and manzanita trees, striking rock formations, and views toward Cahuilla Mountain. The surface is entirely unpaved, combining single-track trail with broad dirt road for a distinctly desert-focused night-running experience. Every circuit brings participants back to an aid station and past their parked cars. That arrangement gives runners regular access to support and personal supplies while they take on multiple loops after dark. A headlamp is mandatory, and trail shoes are strongly recommended because road shoes may provide less stability on the uneven terrain. The race is intended for a wide range of runners. Experienced ultramarathon athletes can settle into the rhythm and strategy of repeated nighttime circuits, while newcomers can experience trail running in a supported loop format. The organizer emphasizes a social atmosphere, with friends sharing the trails as daylight fades and the desert landscape changes under the night sky. Keira Henninger founded the event in 2021, and it continues to be woman-run. The organizers explicitly recognize the Mountain Cahuilla people and express gratitude for being permitted to stage the race on their land. Runners who enjoy off-road terrain, night racing, desert scenery, and a close-knit community setting are likely to find its character especially appealing.

Set at the southern end of New Mexico’s Sangre de Cristo Mountains, the Enchanted Forest Trail Races combine a small mountain town start with rugged forest tracks, alpine ski terrain, and sustained climbing. The races begin and finish at Brandenburg Park in downtown Red River before heading toward Carson National Forest and the Enchanted Forest Cross Country Ski Area. The routes mix a short stretch of pavement with dirt road, jeep track, switchbacks, rolling terrain, and a singletrack trail beside the river. The longer course ventures through dense forest, including a section where a conventional trail may be absent and tree markings guide runners onward. Its defining late challenge is The Face, a steep ski slope visible from town. Runners climb directly up the slope until it meets the trail, continue toward the top of the Platinum lift, and then descend to the base and return to the finish. The Heavy Half follows much of the opening marathon route as an out-and-back course, rewarding its climbing with views of the surrounding peaks and the edge of the Enchanted Forest. The Face Challenge removes the easier connecting miles and concentrates on the ski-area ascent and descent, making it attractive to runners who prefer a shorter but intensely vertical test. The full course is better suited to experienced trail runners looking for dense forest, exposed climbing, and varied mountain surfaces rather than a conventional road marathon. After finishing, runners can gather with family, fellow competitors, and the Red River community for local food, live music, craft microbrews, and free children’s races in the heart of town. The combination of demanding high-country terrain and a community celebration gives the event a distinctly northern New Mexico character.

Set on a pristine island just offshore from Munising, this trail event follows the rugged and remote shoreline of Lake Superior. Runners begin and finish near Williams Landing, with routes reaching places such as Murray Bay, Duck Lake, the island’s narrow tombolo, Trout Bay, Echo Lake, and the western coastal trail. The terrain combines singletrack, two-track paths, narrow dirt roads, forest roads, and sandy beach, giving the race a varied character rather than a single continuous trail surface. The longer routes travel counterclockwise around much of the island. Along the eastern side, runners climb above the shoreline for views toward Pictured Rocks National Lakeshore. Farther north, the landscape features colorful Jacobsville sandstone cliffs rising roughly 300 feet above the water and the isolated setting of North Beach. The return along the western shore opens onto broad views of Lake Superior. Much of the course passes beneath lush hardwood forest, while exposed cliff-top sections receive breezes from the lake. The longest route also turns inland toward Echo Lake and the island’s summit on relatively fast dirt forest roads. The shorter loop has its own distinct progression, passing through dense hemlocks and jack pine before reaching the open beach at Trout Bay. From the sand, it climbs challenging singletrack into the forested highlands, then descends toward the western coast and the finish. This is a strong choice for trail runners drawn to wilderness scenery, changing surfaces, shoreline running, and the unusual logistics and atmosphere of racing on an island. It offers both runnable forest sections and more demanding beach and climbing segments, all framed by the cliffs, woods, bays, and open water of the Great Lakes.

Starting and finishing at the Bartle trailhead just outside McCloud, this trail race follows a former railway corridor through the mountain landscape of Northern California. Every course uses an out-and-back format on an entirely unpaved trail, with views of Mount Shasta accompanying runners along the route. The terrain is described as relatively flat, with good footing and a straightforward line, giving the event a different personality from steep or highly technical mountain ultras. The choice of 10K, 30K, and 50K courses makes the race approachable for several kinds of runner. Newcomers can use the forgiving profile for a first attempt at a longer trail distance, while experienced runners may find the smooth, direct route suitable for pursuing a personal best. The surrounding mountains, forests, and open meadows provide a scenic backdrop, while the old rail bed adds a tangible connection to the area’s logging and railway history. Aid stations are positioned at the course turnaround points, with additional support for the longer distances. All courses have a 12-hour finishing limit, allowing participants in each distance to move through the trail at an appropriate endurance pace. Runners receive a post-race meal, and finishers are awarded a medal. The event also serves as a benefit for the Great Shasta Rail Trail. Proceeds help preserve the historic recreational corridor and support its continued public use. That conservation focus should appeal to destination runners who value locally rooted events, as well as trail athletes looking for an uncomplicated course with mountain views rather than severe climbing or technical terrain.

This compact summer trail race packs forest running, steep climbing, and an unusual river section into a short, demanding course. About 95 percent of the route is unpaved, beginning on winding woodland trails before sending runners for roughly one-third of a mile straight down the Embarras River. In July, the water is described as ankle- to knee-deep, with exposed sandbars and rocky riffles adding constantly changing footing. Water shoes may feel more appropriate than ordinary dry-trail expectations. The challenge continues after the river. With approximately 1,100 feet of elevation gain, the course is exceptionally hilly for its length, and the steep, punchy Billy Goat Hill arrives near the finish to test tired legs. It is a summertime counterpart to the Frozen Cock’s Crow 5K and uses a version of the back half of that event’s course, replacing winter cold with summer heat and a deliberately rowdy atmosphere. A participant limit of 125 keeps the field intimate and supports the quirky, communal character described by the organizer. This race should appeal to trail runners who enjoy technical variety, wet feet, hard climbing, and events where shared stories matter as much as finishing time. It is less suited to anyone seeking a conventional, fast road 5K. After the finish, pancakes and ice cream anchor a social post-race gathering where runners can trade accounts of the river, hills, and heat.

Set on Salida’s S Mountain and the Salida Mountain Trails system, this event combines a national-level championship for high school trail runners with the Beas Knees Citizens Race, which welcomes runners outside the high school field. All competitors test themselves on the same mountain course, making the day relevant both to ambitious young athletes and to experienced community runners who want a genuine trail-running challenge. The route begins on Poblano Trail before connecting with Burn Pile Trail, where a steady climb and a sequence of switchbacks quickly establish the race’s character. The trail initially provides enough width for passing, then reaches County Road 176 for a descent before turning onto Rusty Lung. That narrower trail introduces another sustained climb and leads toward Lil’ Rattler, near the course high point at 7,558 feet. From there, runners descend on Lil’ Rattler and Frontside Trails. The course widens again over its final quarter mile, creating one last opportunity to pass before the finish near Riverside Park in downtown Salida. Switchbacks, climbs, descents, rocks, and flowing singletrack reward more than raw road speed. Runners need climbing strength, confident descending, agility, and the judgment to choose passing opportunities on changing trail widths. The championship crowns individual and team winners for high school boys and girls, while the citizens race is open to all ages and has historically attracted collegiate and masters talent. It is particularly suited to competitive high school runners, cross-country athletes exploring mountain racing, and adult trail runners who want to measure themselves on the championship course. The Beas Knees Citizens Race honors the late Brett Beasley, a U.S. Forest Service ranger known locally as “The Beas,” whose work helped connect people with the outdoors and the Salida trail community.

This low-key, point-to-point ultramarathon crosses Alaska’s Kenai Peninsula on the Resurrection Pass National Recreation Trail, beginning at the trailhead near Cooper Landing and finishing at the northern trailhead in Hope. The route follows a US Forest Service trail once used by early gold miners traveling toward claims along Turnagain Arm, giving the run a strong backcountry identity rather than the atmosphere of a large, fully supported race. From Cooper Landing, runners climb toward Resurrection Pass before turning onto the Devil’s Pass trail around mile 16.5. They descend for approximately six miles to a staffed turnaround, then retrace that section to the junction and continue north toward Hope. The turnaround is the course’s only checkpoint, and its remote position means that aid is limited. Numerous creek crossings provide potential water sources, but organizers advise runners to filter or treat collected water. Long stretches between support points make careful management of food, water, clothing, and safety equipment essential. The entire course is on unpaved trail, with rolling terrain, a substantial out-and-back segment, and an 18-hour cutoff. Conditions in the Kenai Mountains can vary widely, and participants travel through habitat shared with bears and moose. This is therefore best suited to experienced trail and ultramarathon runners who are comfortable moving independently for extended periods and making practical decisions in remote terrain. Athletes drawn to small, mostly self-supported events, historic mountain routes, and a genuine point-to-point wilderness journey will find the format especially distinctive. The race has been held since 1996 and retains an intentionally simple, community-oriented character.

The Squatchy Surprise turns trail running into a game of endurance, chance, and strategy at Summit Field in New Jersey’s South Mountain Reservation. Instead of following one fixed course, participants face four different trail loops. Before each lap, a runner or hiker draws a colored golf ball from a bucket, and that color determines the loop to be completed next. A black ball grants the freedom to choose any loop. Because the sequence is left largely to chance, neither total mileage nor accumulated climbing can be predicted in advance. The terrain mixes firm carriage trails with technical singletrack marked by rocks and roots. The loops vary in length and difficulty, and every one finishes with a rocky descent of about 200 feet. This shifting combination rewards adaptable athletes who enjoy making decisions under fatigue, while the timed format also welcomes people who prefer to run or hike at their own pace. Participants may stop whenever they choose without receiving a DNF, making the event approachable even for those who do not intend to remain on course for the entire allotted period. Volunteers track completed loops with stickers on a large chart, creating a visible, communal record of the day’s progress. Near the finish, participants must decide whether to keep drawing full loops or switch to a short half-mile mini loop; an unfinished loop does not count, so the final choice adds another tactical layer. A single Charity Mulligan allows a disliked draw to be replaced in exchange for a donation, with the proceeds supporting Bigger Than The Trail and its mental-health work. The event also provides a staffed aid area, space for crews, accessibility support, and a quiet tent away from the main hub, reinforcing the organizer’s welcoming trail-party atmosphere.
