Enduro Lite
Enduro Lite categories are a short course option geared toward youth, beginners or racers unable to commit to a full course/day of racing. The short course will be a 2-3 stage condensed version of the full course. Riders should be able to complete a comparable ride of approximately ten miles in length and up to 2000 feet of elevation gain to participate. Parents are welcome to ride with their youth racer 13 years of age and under. Awards ceremony is typically held within 60 minutes of the last Enduro Lite racer finishing the race.



We Want You! Enlistment opens soon for the 

Cascadia Dirt Cup Volunteer Army . It's all thrills and no drills, powered by high fives and hot meals, lots of beverages and lucky raffle tickets (fingers crossed!)

Race Cascadia Rules

Here's a copy of our rules to keep everyone honest, all in the interest of promoting safety, set standards and good sportsmanship so everyone can finish well and have fun. Each racer is responsible for knowing and following these rules.  Failure to comply with these written rules or any other rules communicated to racers at the event may result in penalties or disqualification. Race Cascadia organizers will make any decisions regarding any alleged or potential violation when reported or observed.  



We will be using the touchless Sportident SIAC+ timing system.  Timing chip will go on the racers right wrist only.  No watch or GPS on right wrist.  Please wear on outside of clothing. Lost or unreturned chip will result in a $100 replacement fee and must be paid in full on-site to receive backup times for inclusion in the results for the race, overall series points, and to participate in future events.




Race Cascadia has been producing mountain bike races in the Pacific Northwest since 2012. 

Its signature series, the Cascadia Dirt Cup, is firmly rooted as the Northwest’s premier enduro mountain bike race series.

Race Cascadia continues to create new events, partnerships and opportunities each season to showcase and support the world class trails of Cascadia.
