What to expect at a Big Mountain Enduro event:

The Yeti Cycles Big Mountain Enduro series presented by Shimano, is the premier Enduro series in North America and currently holds stops in the most picturesque vacation destinations throughout the Rocky Mountain region and beyond. This highly anticipated sports entity offers some of the biggest and most challenging racing in and around these mountainous landscapes. With many of the top-ranked trails in the country, BME events tie in big backcountry terrain, as well as combining lift-accessed stages throughout the series. Courses will feature predominantly timed downhill (special) stages linked together by non-timed climbing (liaison) stages.

The 2018 BME will tie in legendary single track and bike park terrain throughout the entire season. Each course is specially designed to give participants a unique riding experience, including high altitude trails and big descents that test athlete’s pure strength, endurance and bike handling skills. In sum, the BME series showcases some of the best trails in North America, while hosting many of the top all-around mountain bikers from across the globe, ultimately catering to all types of riders in an entertaining atmosphere for the entire family and local communities to enjoy.

Established in 2012 and based out of Crested Butte, CO, the Yeti Cycles Big Mountain Enduro presented by Shimano is the premier enduro series in North America. Over the past 6 years, BME has held major events throughout ColoRADo, Utah, New Mexico, the country of Mexico and other projects in the western US. As the years have passed and the sport continues to evolve, the BME has consistently ranked amongst one of the top global enduro events that attracts the top riders in the world, and has remained the only US stop on the Enduro World Series tour for the past four years.

The popular international Enduro racing format encourages spectators and sponsors alike to catch the high-speed, adrenaline-fueled action of all-mountain riding at its finest. Enduro showcases the best all-around trail rider that can tackle any type of terrain, the fastest. Enduro racing turns an epic all day group ride into the ultimate test of fitness and technical skills, while also giving participants a chance to ride some of the best trails in each respective area where BME’s are held.

A Big Mountain Enduro race is best described as an all day trail ride in amazing locations, where you’re timed only on the descents; the most fun part of each trail system. BME events occasionally integrate lift-accessed stages to truly showcase the most challenging trails in each host location and to maximize the vertical descending at each event.


The Big Mountain Enduro owns and manages state of the art timing systems powered by Sport iDent, that will be a vital element to the reliability and accuracy of each race and the overall rider experience. Expect to see a combination of high speed chip technology software systems, along with active card readers and live data check-point systems that are more effective for backcountry stages, ultimately delivering a world-class race experience and accurate and timely results for all riders.

The 2018 Yeti Cycles Big Mountain Enduro presented by Shimano consists of four series points events – Santa Fe, NM, Crested Butte, CO, Keystone, CO, and Aspen Snowmass, CO.

Series Rules:

The beauty of Enduro racing is that it brings us all back to the roots of mountain biking. It is ungoverned, unregulated and each event capitalizes on what it has to offer naturally. And we at BME want to keep it that way. That said, we feel it is in the best interest and safety of all of our competitors to have a few rules in place to make sure competition is fair, friendly and there are no communication gaps.
