What is Enduro Mountain Biking? | Enduro MTB Racing Explained



What is Enduro Racing?

    There are several disciplines of mountain bike racing, with the two OG’s and still most popular being cross country and downhill. These races have been going on for decades, and while they aren’t going anywhere anytime soon, a new foe has appeared.

    Enduro racing has been exploding in popularity the past few years, and has been taking some of the spotlight away from cross country and downhill. But wait a second, what exactly is enduro? In downhill, you’re racing down the trails, in cross country, you’re racing up and down the trails, and enduro is somewhere in the middle?

    Well, that’s kind of it! Enduro races are made up of several timed downhill stages with untimed transfer stages in between them. In an enduro race, the times of all of your timed downhill stages are

added together for your cumulative time, and at the end of the day, the rider with the lowest cumulative time is the winner. This format of stage racing is nothing new, with its origins dating back over 100 years to motorcycle racing in England. Stage racing is also hugely popular in rally races, road races, and even NASCAR!

"Enduro races are made up of several timed downhill stages with untimed transfer stages in between them."


Un-timed Transfer Stages

    First, let’s take a closer look at those untimed transfer stages. They come in a few different flavors, but they are all meant to bridge the gap between the bottom of the previous stage to the top of the next stage. This could mean pedaling up the hill, coasting down the hill, taking a chairlift up, or, if you’re lucky, the next stage starts right where the last one ended. Even though these are untimed sections of the race, some races will have cut-off times, which is a maximum amount of time you are given to complete the transfer stage. These are usually reserved for the highest caliber of races, such as the Enduro World Series, and most local races are pretty lenient in the amount of time you can take. The most common type of transfer is simply pedaling back up the hill, and is an element of every proper enduro race. Lots of races are hosted at bike parks, which will often have their ski lifts modified to accept bikes during the summer months, so sometimes you get the luxury of a lift to the top. Most bike park races that are hosted at bike parks have some pedal transfers and some lift transfers because usually the lifts don’t go to the top of each of the stages. But once you get to the top of the stage, that’s when the fun begins.

Timed Stages

    The timed stages are primarily downhill and the real reason why we put up with the transfers. There can be a huge variation in the difficulty of trails raced, ranging from borderline cross country trails to full on downhill tracks. On those cross country trails with lots of pedaling, physical fitness plays a huge role in who comes out on top, while the winners on gnarly downhill tracks are determined by their technical skills on the bike. The nature of tracks that get raced depend entirely on the trail system that the race is being hosted on, which can be anywhere from a local hill with a few fun trails to the biggest bike parks in the world, like Whistler or Queenstown.

    On the day before the race, there will be a practice day where riders will practice each of the stages one time, taking their time to pick the fastest lines. Part of the nature of enduro is not memorizing every part of the track, and being forced to think on your feet come race day. Lots of riders will record their practice runs on helmet cams to review that night, but it’s almost impossible to really memorize all the tracks.

So why has Enduro been gaining so much popularity recently?

    I think the main factor is how capable modern enduro bikes have become. To ride burly trails the way we really want to, you used to need to shuttle with downhill bikes, but now we can just pedal our efficient trail bikes to the top and still enjoy all the technical trail features. And most people are more interested in a race that’s similar to the kind of riding they do back at home. Also, compared to racing downhill where you only get one 5 minute race run, you get to spend all day out on your bike at an enduro race, with total race times sometimes getting close to the hour mark. One of my favorite aspects of enduro races is that they typically have a more laid back atmosphere than a downhill or cross country race where everyone is hyper focused on results. While there is definitely still that competitive spirit in enduro while racing against each other down the hill, it just feels like another bike ride when cruising back up the transfer stages with the other racers.


The Bikes

"Most enduro bikes are built around 150 to 170mm of suspension travel in the rear and 160 to 180mm in the front."

    Last but not least, let’s take a look at the bikes that make this kind of racing possible. Like we mentioned earlier, these bikes are efficient enough on the climbs to get racers back to the top of the hill but they’re really designed for getting down the hill as fast as the rider dares to. Most enduro bikes are built around 150 to 170mm of suspension travel in the rear and 160 to 180mm in the front. Some riders will run a coil shock, while others will run an air shock, depending on the suspension design of the bike they’re running and also their personal preference. All racers will also be running strong 4 piston brakes with big rotors at least 180 mil in diameter, as well as thicker casing tires, sometimes even as thick as a downhill casing. It’s also super common to run inserts inside of these tires, just so you can keep on riding in case of a flat as well as all of the other benefits inserts provide. All of the parts that get put on these bikes are chosen with durability and reliability in mind, because they have to make through an entire day of abuse. Oftentimes, these enduro bikes actually get thrashed even harder than downhill bikes because things can go wrong pretty quickly when pinning down a track that you aren’t that familiar with.


Hopefully this answers some of your questions about this new breed of mountain bike racing, and I hope you enjoyed this different style of post.
