The Bear 100 Race Guide
When It Is Run
The Bear 100 takes place annually on the last Friday of September, specifically Friday, September 26, 2025. The race starts at 6:00 AM sharp from Hyrum Gibbons/Mount Logan Park in Logan, Utah. This timing places the event during peak fall foliage season in the Wasatch-Cache National Forest, when the aspens display brilliant yellow colors and maples turn vibrant red against the backdrop of evergreen forests. The late September date provides cooler temperatures that are ideal for the demanding mountain terrain, though runners must be prepared for unpredictable weather that can range from pleasant daytime conditions to potential snow at higher elevations. Participants have a generous 36-hour time limit to complete the course, with the final cutoff at 6:00 PM on Saturday, September 27. The race finishes at Bear Lake in Fish Haven, Idaho, creating a stunning point-to-point journey through some of the most scenic mountain country in the intermountain west.
How to Qualify or Register
Registration for The Bear 100 operates on a first-come, first-served basis that opens December 1st at 8:00 AM Mountain Standard Time and typically fills within 10 minutes. To register, runners must have completed at least one official race of 50 miles or longer with a finishing time under the race cutoff within the four years prior to registration (qualifying window December 1, 2020 – December 1, 2024). For 50-mile qualifiers specifically, runners must have finished in under 16 hours, while any 100K, 100-mile, or 200-mile finish under the cutoff qualifies regardless of time. All qualifiers are verified through Ultrasignup or official race websites, and registrants who cannot provide valid qualification will forfeit their entry. Beyond the running qualification, all participants must complete 8 hours of volunteer service either through trail work or volunteering at an ultramarathon between September 26, 2024, and September 15, 2025. The entry fee is $350 plus taxes and fees, and the race maintains a waitlist capped at 400 people. Starting in 2026, the race will transition to a lottery system due to overwhelming demand.
Particular Challenges
The Bear 100 presents numerous formidable challenges that make it one of the most demanding 100-mile races in the country, earning its reputation as a Hardrock and Western States 100 qualifier. The primary difficulty lies in the massive 22,000 feet of elevation gain over varied mountain terrain that includes 12 significant climbs according to experienced participants. The course ranges from 5,000 feet at the start in Logan to over 9,200 feet at the highest points, creating altitude challenges for runners not accustomed to high elevation. Weather presents another major challenge, as late September conditions in the Wasatch Mountains can be highly unpredictable, ranging from pleasant fall temperatures to sudden storms that may bring rain, snow, or freezing conditions. The technical nature of much of the course, particularly the rocky descents and steep climbs, demands careful foot placement and can be treacherous in the dark or wet conditions. Navigation can be challenging in several sections where cattle have created multiple trail braids, and some critical turns are extremely difficult to spot without careful attention to course markings. The remote wilderness setting means that if runners encounter serious problems, rescue can be complicated and time-consuming.
Course Format
The Bear 100 follows a point-to-point format that begins in Logan, Utah, and finishes 100 miles later at Bear Lake in Fish Haven, Idaho. The course traverses the Wasatch-Cache National Forest and the Bear River Range, creating a challenging mountain journey through some of the most spectacular wilderness in Utah and Idaho. Unlike loop courses where runners return to familiar territory, the point-to-point design means participants experience constantly changing scenery and terrain throughout the race. The course travels through diverse ecosystems, from the dry canyon starts near Logan through alpine forest with towering pines, across high mountain passes, and finally descending to the beautiful Bear Lake valley. This format creates unique logistical challenges for crews and pacers, as support teams must drive considerable distances on mountain roads to reach aid stations. The point-to-point nature also means that all runners must arrange transportation from the finish back to Logan to retrieve vehicles, though the race provides some shuttle services. The course’s design showcases the full beauty of fall colors in the region, as runners pass through brilliant aspen groves and red maple stands that create one of the most scenic 100-mile experiences available.
Elevation Profile
The Bear 100 features one of the most challenging elevation profiles of any 100-mile race, with approximately 22,000 feet of total elevation gain over the course. The race starts at roughly 5,000 feet elevation in Logan, Utah, and reaches its highest points above 9,200 feet in the Wasatch-Cache National Forest. The elevation profile includes 12 significant climbs of varying difficulty, with the steepest and most notorious being the “Ranger Dip Liftoff” near mile 93, which runners describe as going “straight up the mountain”. The first major climb from the start is the longest continuous ascent, gaining approximately 3,000 feet over the initial 10 miles to Logan Peak. Other major elevation gains include the climb to Tony Grove at mile 52, the ascent to Franklin Basin around mile 62, and the challenging climbs through Gibson Basin after mile 80. The course features not just climbs but also significant descents, including some that are described as “rocky and steep” requiring careful navigation. The final major climb occurs at Ranger Dip around mile 93, where runners face the steepest ascent of the entire race before the final 4,000-foot descent to Bear Lake. The high altitude component adds another layer of difficulty, as much of the race occurs above 7,000 feet elevation where oxygen levels are reduced.
Terrain Breakdown
The Bear 100 course consists of approximately 70% singletrack trail and 30% dirt roads, creating a predominantly technical trail running experience. The singletrack portions feature varied surfaces including rocky technical sections, smooth forest trails, root-covered paths through aspen groves, and exposed ridge lines with loose rock. The trail surfaces range from well-maintained forest service paths to challenging rocky descents that require careful foot placement, particularly in areas described as “bears’ teeth” due to the sharp rock formations. Many sections of the course feature heavily braided cattle trails where livestock have created multiple parallel paths, requiring runners to pay close attention to course markings to stay on the correct route. The dirt road sections provide some relief from technical terrain but often involve significant climbs or descents on forest service roads. Stream crossings occur at several points, including the Logan River crossing around mile 69 where runners may get their feet wet. The course passes through diverse terrain types, from dry sagebrush areas in canyon bottoms to dense coniferous forests at higher elevations, and open meadows filled with wildflowers and aspen groves. Some sections feature challenging footing on loose rock, while others provide smooth running on packed dirt trails through scenic forest corridors.
Time Limit and Cutoffs
The Bear 100 provides a 36-hour time limit for all participants, with the race finishing at 6:00 PM on Saturday, September 27, 2025. The race implements specific intermediate cutoff times at each of the 12 aid stations to ensure runners maintain adequate pace to finish within the overall time limit. While the specific cutoff times for 2025 were not detailed in available sources, historical patterns show that cutoffs become progressively tighter as the race progresses, with the most critical checkpoints typically occurring at Temple Fork (mile 45), Tony Grove (mile 52), and Franklin Basin (mile 62). Runners who fall behind the required pace at any aid station will be stopped by race officials and are not permitted to continue. The generous 36-hour limit accommodates the challenging terrain and significant elevation gain, allowing even slower runners a reasonable opportunity to finish if they maintain steady forward progress. Night running is almost inevitable for most participants, as only the fastest runners will complete the course during daylight hours. Cutoff enforcement becomes particularly strict during the final third of the race, where the most challenging climbs and technical terrain can slow runners significantly. Race officials at aid stations monitor runner conditions carefully and may also stop participants who appear unable to continue safely, regardless of whether they are within the time cutoffs.
Aid Stations
The Bear 100 features twelve aid stations strategically positioned throughout the 100-mile course, providing runners with regular opportunities for resupply and support. The aid stations are spaced approximately every 8-10 miles, which is considered reasonable spacing for the challenging mountain terrain. Major crew-accessible aid stations include Right Hand Fork (mile 37), Temple Fork (mile 44.8), Tony Grove (mile 51), Franklin Basin (mile 62), Cowley Canyon (mile 69), Logan River (mile 75), Beaver Mountain Lodge (mile 89), and Beaver Creek Campground (mile 95). Due to limited parking space, crews are restricted to accessing only one of two early stations – either Right Hand Fork or Temple Fork – and must choose their preference during registration. Most aid stations allow drop bags, though runners are encouraged to keep them to reasonable sizes, and all drop bags are transported to the finish line for pickup after the race. Aid stations are fully stocked with traditional ultra foods including fruit, sandwiches, soup, energy drinks, and various snacks, plus the race provides Gnarly Fuel2O endurance drinks and GU Energy products at all locations. The Bear 100 operates as a “cupless” race, requiring all participants to carry their own drinking containers, though limited cups may be provided for soup consumption.
Mandatory Gear
The Bear 100 has relatively minimal mandatory gear requirements compared to many mountain ultra races, focusing on essential safety items rather than extensive equipment lists. All participants must carry a headlamp with spare batteries or backup light source since most runners will be on course during nighttime hours. Runners are required to have adequate hydration capacity, typically interpreted as bottles or bladder systems that can hold sufficient water between aid stations. The race strongly recommends carrying warm layers appropriate for mountain conditions, including jacket, hat, and gloves, as September weather in the Wasatch Mountains can be highly variable. Unlike many technical mountain races, The Bear 100 does not require GPS devices, emergency shelters, or extensive first aid kits, reflecting the relatively well-marked course and accessible terrain. Participants are encouraged to carry extra food and calories beyond what aid stations provide, especially if they have specific nutritional needs or preferences. The race emphasizes personal responsibility and self-sufficiency, expecting runners to prepare appropriately for mountain conditions without mandating extensive gear lists that might discourage participation.
Crew and Pacing
The Bear 100 is moderately crew-friendly, allowing support teams access to seven of the twelve aid stations throughout the course. Crews receive one vehicle pass per runner and must display proper credentials to access aid station parking areas. The unique restriction requires crews to choose between accessing Right Hand Fork (mile 37) or Temple Fork (mile 44.8) during registration, as both stations cannot accommodate all crew vehicles due to space limitations. Pacing is allowed starting at mile 50 (Tony Grove aid station), meaning pacers can join runners for the final 50 miles of the race. Only one pacer is permitted at a time until the final mile, where multiple pacers may accompany the runner. Pacers must check in and out at aid stations with race officials and are subject to the same rules as runners, including no “muling” or carrying supplies for their runner. All pacers must complete a waiver before the race and follow proper protocols at aid stations. Crew vehicles must observe all traffic laws on mountain roads and are not permitted to provide aid outside of designated aid stations. The remote mountain setting means crew travel between stations can involve significant driving distances on forest service roads, requiring careful planning and adequate time between aid station visits.
Navigation
Course marking for The Bear 100 is excellent and comprehensive, utilizing reflective markers, flagging tape, and signage throughout the 100-mile route. The race organizers place particular attention to marking critical turns and intersections where runners might take wrong paths, especially in areas where cattle have created multiple trail braids. GPS devices are not required since the course is well-marked with traditional trail marking methods, though many runners choose to carry GPS units for additional security. The marking system includes frequent mile markers to help runners track their progress and pacing throughout the race. Race directors emphasize that while markings are excellent, they are not “idiot-proof” or “zombie-runner-proof,” requiring runners to pay attention and prepare by studying course maps in advance. Critical navigation points include several stream crossings, cattle gate passages, and turns from singletrack trails onto forest service roads. The course passes through various terrains including dense forest, open meadows, and ridge lines, with markings visible both during daylight and with headlamps during nighttime running. Race officials conduct thorough course marking inspections before the event and may add additional markers in problematic areas based on previous years’ experiences.
Finish Rates
The Bear 100 maintains finish rates between 60-75% depending on weather conditions and course challenges in any given year. The 2022 race achieved the highest finish rate in event history at 75% with 235 finishers out of 313 starters, while more challenging years have seen rates drop to around 60%. Historical data shows that finish rates have generally improved over the years as the race has matured and course marking has been refined. Weather plays a significant role in completion percentages, with hot years like 2014 producing lower finish rates due to dehydration challenges, while snow and cold conditions can also impact success rates. The 36-hour time limit is considered generous for the course difficulty, allowing most prepared runners adequate time to complete the distance if they maintain steady forward progress. Factors contributing to DNFs include underestimating the cumulative effect of 22,000 feet of elevation gain, navigation errors in challenging sections, weather-related problems, and the mental challenges of running through two nights. The race’s point-to-point format means that runners who drop out often face complicated logistics to return to the start, which may motivate some to continue when they might otherwise quit in a loop race. The Bear 100’s finish rate compares favorably to other challenging 100-mile mountain races, reflecting good course support and management while maintaining the difficulty that makes it a respected qualifier for Western States and Hardrock.
Special Features
The Bear 100 offers several unique features that distinguish it from other 100-mile races, most notably its designation as both a Western States 100 and Hardrock 100 qualifier, making it attractive to runners seeking entry into those prestigious events. The race awards distinctive belt buckles to all finishers, with special sub-24 hour buckles for those achieving that time standard. A special $1,000 cash prize awaits any runner who breaks either the men’s or women’s course record. The event is part of the Rocky Mountain Slam, which runners complete by finishing Hardrock 100 plus three of four other Rocky Mountain races including Bear 100, Leadville 100, Bighorn 100, or Wasatch Front 100. The race’s “36 Hours of Indian Summer” motto reflects the spectacular fall foliage that typically occurs during the late September timing. The point-to-point course from Logan, Utah to Bear Lake, Idaho creates a unique interstate journey that showcases diverse mountain ecosystems and terrain types. The race maintains strong environmental stewardship, operating as a cupless event and emphasizing Leave No Trace principles throughout the Wasatch-Cache National Forest. The Bear 100 also hosts shorter distance events including a 50-mile race and trail marathons, creating a weekend festival atmosphere. The race’s high elevation profile, averaging 7,700 feet, makes it excellent training for other high-altitude mountain races.
