Just try to keep your eyes on the trail at Pierre's Hole 100, one of the best MTB events in the Rockies, as the racecourse is located at the base of the stunning Tetons near Grand Targhee Resort and offers many breathtaking views. The event is part of the prestigious National Ultra Endurance Series (NUE), and although the course is not super technical, it doesn’t give you many areas to relax, including one new section of trail called “38 special” because it has 38 bermed turns. Two-course options with limited registration are available for each: only 250 spots for the 100k and 300 spots for the 50k.
Event & Course Info
The racecourse singletrack is longer and better than ever, and the rugged terrain will test you. The course will have the start/ finish just off the main plaza at Grand Targhee Resort. The 100k and 50k routes utilize a similar loop with a few variations spanning 25-31 miles and 3,600-3,800 feet of elevation gain. Naturally, the 100k event requires two loops with a total elevation gain reaching over 7,000 feet. There is a fully stocked aid station about halfway, one just after the start/finish, and a bike wash for after the event. Check out the detailed course maps below. After the event, refuel with food, drink, and camaraderie at Wild Bill's.
Pierre’s Hole, once known for the fur trade in the Northern Rockies, has always been a test of endurance, fortitude, and strength.
Area Accommodations & Things to Do
Grand Targhee Resort offers ample lodging and amenities that await Pierre's Hole 100 racers and their families. Camping is available for participants in the lower parking area with a reservation, while Reunion Flat and Teton Canyon are two other nearby campgrounds. For those looking to stay outside of the resort, there are vacation rental options to explore, such as this large home that would be great for a family or group, this quaint cabin, or a nature lodge.
There is abundant hiking at Grand Targhee for racers and families to enjoy during their weekend. The Bannock Trail is a favorite among many visitors, offering a moderate hike that takes you through wildflower-filled meadows and dense forests. The highlight of the Bannock Trail is the picturesque views of the Grand Teton and the surrounding mountains. It's a great option for hikers of various skill levels, and the scenery makes it a rewarding experience. If you're looking for a more challenging hike, the Targhee Ridge Trail is a fantastic choice. This trail leads you along the mountain ridge, providing breathtaking vistas of the Teton Range and the valleys below. Be prepared for some elevation gain, but the sweeping panoramas make it well worth the effort. The Snooze Lake Trail is a rewarding choice if you're up for a longer hike. The trail leads to a serene alpine lake nestled in the mountains. The hike involves a moderate ascent, but the tranquil lake surrounded by rugged peaks makes for a memorable destination.
If you're an outdoor athlete who enjoys fishing, the resort's proximity to world-class rivers and streams makes it a fly-fishing paradise. The nearby Teton River and the South Fork of the Snake River are renowned for their trout fishing. Guided fly-fishing trips are available for beginners and experienced anglers, allowing you to explore the best fishing spots and hone your fly-casting skills. The serene and picturesque setting adds to the allure of the experience, creating a perfect day of relaxation and adventure.
It can't be forgotten that Jackson Hole is under 1.5 hrs drive which offers endless options for activities, restaurants, lodging and access to National Parks.
About the National Ultra Endurance (NUE) Series
The National Ultra Endurance (NUE) MTB Series is one of the premier mountain biking race series in North America, dedicated to ultra-distance mountain biking enthusiasts. The series is composed of Epic Series events, which are grueling 100-mile races, and Marathon Series events, which are 50-mile to 100k length races. Each race/event challenges riders' endurance, technical skills, and determination on some of the country's most scenic and rugged courses. The NUE Series was established in the early 2000s to provide a competitive long-distance mountain biking platform. Its goal was to elevate ultra-endurance mountain bike racing and build a community of athletes passionate about pushing their limits. Over the years, it has expanded to include multiple events spanning diverse terrains across the US and several global locations. In 2025, the Series final takes place at the Oak Ass 100/50 in Alabama.
Participation in individual NUE events is open to all riders, but registration fills quickly due to the series' popularity. Riders must complete at least three events to qualify for overall series rankings, with points awarded based on finishing positions and the best four results counting toward their total score. Categories include Open Men, Open Women, Master 50+ Men, Master 50+ Women, and Singlespeed, with all participants required to meet strict time cutoffs to be considered finishers. The series offers significant rewards, including cash prizes, custom jerseys, trophies, and recognition for top finishers, while providing a platform for riders to gain exposure, attract sponsorships, and join the ranks of endurance mountain biking legends.
The National Ultra Endurance MTB Series is not just about racing—it's a celebration of mountain biking culture, showcasing breathtaking courses, fostering community, and pushing the boundaries of what riders can achieve. Whether you're a seasoned pro or an aspiring ultra-endurance athlete, the NUE Series offers an unforgettable experience.
