Big Mountain Enduro worked with Enduro World Series from 2014-2018, to host the only top-level international Enduro events in the United States during that timeframe. Past EWS stops managed by BME have included Winter Park, Crested Butte and Aspen Snowmass. BME was the first and only US-based organization to produce events of this caliber.

“The Enduro Worlds Series has worked with Big Mountain Enduro for the past 4 years and our USA calendar entry has always included a welcome visit to Colorado. The BME team deliver a great series with adventure, epic trails and rider experience at its heart, all values we share at EWS.” -Chris Ball, Director Enduro World Series


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 events 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 integrate lift-access and pedal transfer stages to truly showcase the most challenging trails in each host location and to maximize the vertical descending and racer experience at each event.

The 2021 Yeti Cycles Big Mountain Enduro presented by Maxxis tour consists of five series points events. Three of the five tour stops will count towards series points, so two races can be dropped. If you race the entire series, your lowest two scores will be dropped, factoring in only your top three respective finishes. The BME series overall title will be awarded to the athlete with the most points (from 3 of the 5 events) following the 2021 Finals in Brian Head, UT.

The overall winner of the BME series will be titled the 2021 Yeti Cycles Big Mountain Enduro presented by Maxxis Overall Champion. Top three rounds of the BME will count towards the overall points and rankings and based on the point structure system below. Each event is worth up to 400 points.

BME will require face coverings in all public areas, including the sponsor village, at registration check in, while loading/unloading chair lifts and throughout the base area of each host resort. Racers can remove face coverings once on the lifts, during pedal transitions and while racing. Otherwise face coverings must be worn at all times. Additionally, BME will be conducting temperature checks on all racers at registration and packet pick up on Friday, along with a symptoms checklist to ensure all racers do not have signs of the virus. Our staff will also be conducting the same tests on all BME employees, volunteers and resort operations crew. If a racer does have a fever (over 100.4 degrees) or COVID related symptoms, they will not be allowed to race and will be offered a refund for their entry. If anyone is showing any signs or symptoms of COVID before heading to each respective event, we ask you to stay home and quarantine yourself, and we will work with you on your registration.

New for this year, BME will be offering e-bike categories at the Ironton, Santa Fe, Big Sky and Winter Park events. At this time, Brian Head, UT does not allow e-bikes. 3 out of 4 of the aforementioned tour stops (Stops 1-4) will count towards series points and rankings for the e-bike division.

The E-bike categories will ride the same courses as all other categories at each venue, with the exception of minor changes and small climbs added at the race director’s discretion. The courses raced will share similar stages with the BME, with the exception of some of the following changes:

1. Fewer chairlifts where applicable.

2. More time on the bike via pedal transitions.

3. Some timed uphill sections integrated into some race stages.

4. Shorter overall time to complete the day.

The course will vary depending on the event location and will be subject to change as determined fit by the race director. The E-bike race categories will have a MINIMUM of one ‘positive grade stages’. Positive grade stages will be a combination of two descending stages with a short technical climb connecting descents; i.e. Super D style format.

BME 2021 Rulebook


Download the 2021 Rulebook here.

The Yeti Cycles Big Mountain Enduro, presented by Maxxis will offer a Beginner division for all 2021 BME events. Due to the demand of new racers looking to enter the sport of enduro and compete in major events, this category will provide racers an opportunity to ride the same courses as the Pros and Amateurs, with minor trail adjustments made to offer less technically demanding stages. The Beginner category will race all stages and follow the same schedule as other categories, while still delivering the world-class racing experience and camaraderie that the BME community is known for. It is highly recommended to know what you are getting into and to practice all stages to familiarize yourself with the terrain and technical features before race day.

Any type of rider can race a BME event. From amateurs to the top level pro racer, our races suit all skill sets for every caliber of rider, including juniors and first-time beginner racers. But rest assured, BME events are not for the faint of heart and our race series is one of the most challenging in North America and does entail technical features, which include black diamond and double black diamond trails. Those racing a BME event will walk away a stronger, more confident rider, while building new friendships and camaraderie along the way.

Yes, the BME fully supports the up-and-coming youth and junior development aimed at mountain biking and a healthy lifestyle. The “Groms” category is designed for racers between the ages of 10-16; the future of our sport. We welcome all kids and parents to get involved with the BME and our ever-growing mountain bike community.

There is no part swapping during the race. That includes suspension, wheels and frame (front and rear triangles). The BME typically has tech support in the BME sponsor village area, although some part replacements can result in a time penalty or disqualification, so know the rules and read the official rulebook for those important details. Any competitor caught swapping parts or receiving outside assistance from a non-racer without prior agreement from the Race Director will be disqualified. This includes using team support or outside help to carry equipment on the race course or performing repairs during the race.

Gonna need a few things looked at.

All riders must wear a helmet during competition, during both Liaison and Special Stages. Full face helmets are recommended for most venues. The helmet should meet the regulations set by the event organizer. The correct fitting, condition and suitability of the rider’s helmet is the sole responsibility of the rider.

A two-piece helmet (with removable jaw piece) will be accepted as a full face helmet. However, due to national insurance and federation regulations any helmet used in an event must pass the standards of national regulations. Further information may be found in the Rulebook for each event.

Specific body protection and helmet requirements may also be stipulated at each event in accordance with that territory’s national regulations. Any protection rules put in place by the organizer must be followed by all competitors. No exceptions will be permitted. Depending on the venue and access to the tech/pit area, riders can carry protective gear with them, so long as it does not break the part replacement rules. Each rider must be self-sufficient during the entire duration of the race (food stashes are not permitted). Personal responsibility and self-sufficiency are a large part of the spirit of enduro racing and riders are encouraged to carry adequate gear for operating in mountainous environments. Each rider should remember that they are solely responsible for themselves but are urged help other competitors on course.
