Ride the Dirt Wave 

Klootchy Creek ~ Whiskey Run ~ Newport


Get ready for the Flow Duro Challenge – it’s like your favorite Enduro race but with an extra dose of fun! This ultimate test for mountain bikers is all about community, competition, and an unbeatable experience. We’ve handpicked the best terrain at each location for an epic ride.

Here’s the deal: you’ll compete individually on trails that push your skills and stamina to the limit. Our format keeps the spirit of Enduro alive while letting each event shine with its unique flair. So saddle up, get ready to shred, and let the adventure begin!

This race is limited to 125 riders.  Racers will be placed in divisions by age and class and have two timed runs on trail.  Best time is kept and points will be awarded to top 10 finishers overall.  Points will be assigned after each race and posted on the OBRA website.  Points will accumulate for all 3 races in 2024. You must race in all 3 events to be eligible to win the series championship.  The “Champion of the Dirt Wave” will be determined after the final race in Newport.    

Points: The top ten men & women at each series event (Overall Winners), on a traditional mountain bike and on an e-bike will receive points respectively towards the series total. A category distinction of Cat 1 (Expert) or Cat 2 (Sport) does not factor into series points, nor does age.

* Participants must compete in all three series events to be eligible for end of series championship awards.

Category Descriptions:

Please read the following descriptions to determine what category is most appropriate for you.  We advise you to look at the trail forks information for each of the races as all differ in difficulty, length, elevation, and terrain.

Cat 1 (Expert) riders are highly skilled and comfortable with a wide range of obstacles encountered on a trail, including steep and loose terrain and technical rock gardens. They can navigate most trail features confidently including black diamond trails that may have jump lines and larger obstacles.

Cat 2 (Sport) riders possess the ability to handle technical terrain, smaller jumps and drops, and are skilled at cornering. They are capable of completing most trails without stopping to walk a section, but may choose to go around larger jumps or drops. While some may have racing experience, it is not a requirement for a sport rider.
