Event for 2027 has not been confirmed yet… Nestled in the historic gold-rush town of Auburn, CA, the birthplace of mountain ultras, lies a trail runner’s dream event: The Canyons Endurance Runs by UTMB 2027. Produced in partnership with Epic Endurance Events, who bring you NorCal’s most epic mountain, ultra, and trail running events, this prestigious event acts as the UTMB World Series Americas Major and is considered by our team to be one of the Best Trail Running Events in the Southwest. As a qualifier for both the UTMB World Series Finals (earn eight stones!) and the Western States 100, the Canyons Endurance Runs offer a unique opportunity for runners to test their limits and earn their spot in some of the most iconic ultra-marathons globally. Also notable is the Canyons 100K, a Western States 100 Golden Ticket race offering the top two female and male finishers direct entry to the legendary Western States 100.

The Canyons Endurance Runs by UTMB start in downtown Auburn, known as the “Endurance Capital of the World,” which is a fitting stage for this event, boasting a rich history of hosting iconic endurance races. A variety of distance options are offered, including the 100M, 100K, 50K, and 25K. The Canyons Endurance Runs immerse participants in the picturesque and challenging landscapes of the Sierra Nevada range. Runners will traverse historic trails, echoing the footsteps of 19th-century prospectors, and experience sections of the renowned Western States Trail.

The 100M race begins at China Wall, leading runners through Eldorado Canyon, Deadwood, and past the iconic Swinging Bridge. The route includes a descent to Eldorado Bridge, a journey through Volcano Canyon to Foresthill, and a run along the American River. With approximately 18,000 feet of vertical gain and 22,000 feet of descent, this course promises to be both breathtaking and challenging.

The 100K route, offering views and challenging terrain, includes notable sections like the descent from Devils Thumb to Swinging Bridge and a reverse journey from the 2022 edition. The 50K course captures the spirit of Sierra trail running, starting and finishing in downtown Auburn. It covers the American River canyons and includes steep climbs and fast descents along well-trodden trails. There is also a 25k covering 15.5 miles and nearly 2,800 ft of elevation gain.

Mandatory gear includes a minimum water supply of 1 liter, a reusable cup, a running pack, a mobile phone with international roaming, two headlamps with spare batteries, a jacket with a hood, and a hat.

The Canyons Endurance Runs by UTMB are not only a test of physical endurance but also a celebration of trail running culture. The event includes post-race celebrations, awards ceremonies, and various festivities, fostering a sense of community and achievement among participants. The race embodies UTMB’s commitment to equal rights and opportunities, with ongoing efforts to enhance inclusivity and diversity in trail running.
