THE NORTHWEST PREMIERE ENDURO SERIES.

The Cascadia Dirt Cup is a six race Enduro series that takes racers through out the Pacific North West on a tour of the best trails the region has to offer. With a best “4 rounds out of 6” points structure racers are encouraged to make as many rounds as they can to compete for the series overall in their Category.

Each course is comprised of a series of untimed climbs and timed descents. Go up with the pals, but there are no friends on a loam day when gravity takes over. At the end of the day it’s the cumulative time of the stages that dictate the winner, so don’t get cocky. You gotta finish the day to take the #1.

up to 6 stages of racing

Over 20 minutes race time on the Expert Course

contactless timing.

The best trails the PNW has to offer.

$350,000 donated back to trail work since 2013.

Same course,
Same Support,
Same Great race.

THE KIDS ARE ALRIGHT.

At the Cascadia Dirt Cup we believe that the future of mountain biking starts now, and starts here. Youth will be racing the same stages, in the same order as the adults. We have pit space for the teams, and youth racing is a great opportunity for parents to hope on course and watch the kids throw down. Volunteer to time a stage, be a course marshal, or just head out and heckle, we provide a multitude of ways to participate without racing.
