Raging River State Forest, Washington
Mtb cycling event
Rip through the lush trails beneath Mount Si in this enduro race that doubles as the perfect Sturdy Dirty warm-up.
Round #2 of the 2026 Cascadia Dirt Cup heads to the Raging River trail system, nestled in the shadow of iconic Mount Si east of Seattle. Practice opens on May 22nd with racing on May 23rd, giving riders a full weekend to soak in some of the region's most rewarding singletrack. Organizers pitch this one as part physical therapy, part race prep, and part scenic escape—and they're not wrong. The Raging River network blends flowy descents with punchy technical sections, making it an ideal proving ground for riders looking to sharpen their skills ahead of bigger challenges later in the season. If you're eyeing the Sturdy Dirty, consider this your mandatory tune-up.
