While mountain biking has been around since the 1970’s, it still has more of a grassroots feel compared to road cycling. Road bike races have formal institutions like the Tour de France while the downhill mountain bike race series’ are more regionalized. So, what does that imply for mountain biking fans? It means you can see professional caliber racing in your own neck of the woods! Here’s a guide to the Best Mountain Bike Racing Series out there across the US.

Before we jump into the racing series’, we want to first explain the differences between each mountain biking discipline.

  • Cross-Country – The most popular of all the mountain biking events. It involves competitors racing point-to-point via a defined course where the person with the fastest time wins. The XC trails can range from fire roads to winding narrow single-tracks.
  • Downhill – This is THE event for adrenaline junkies. People who feel the need… the need for speed! It involves jumping off cliffs, rock gardens and everything else a mountain trail can throw at them. Full-face helmets, body armor and chest protectors are the normal uniform for these competitors.
  • Enduro – A combination of downhill and cross-country into one event. This is the all-mountain event. Click here to read the full explanation of this awesome match-up.

Cascadia Dirt Cup – Pacific Northwest

Race Type: Enduro

The Cascadia Dirt Cup is the Northwest’s premiere Enduro mountain bike race series and not just for the races, but also as an incubator for the NW MTB community to grow. How? This Enduro series does it by making each event available to all levels AND by donating their proceeds to local trail stewards. In addition to the funding, they also contribute over a 1,000+ hours of trail work through the Work-Eat-Shred program. A great series with a great cause! Unfortunately, for 2020 the race has been cancelled. Let’s hope 2021 brings back a MONSTER of races.
