Tiger Mountain State Forest, Washington
Mtb cycling event
Embrace the mud, channel your inner predator, and survive the infamous Tiger Mountain soaker in Round #4 of the Cascadia Dirt Cup.
Round #4 of the 2026 Cascadia Dirt Cup descends upon Tiger Mountain State Forest—a venue so notoriously wet that organizers joke about bringing rain to July. Practice opens July 24th with racing on July 25th, and riders should come prepared for conditions that range from damp to downright biblical. Tiger Mountain's dense forest canopy, rooty descents, and slick clay soil make this one of the most technically demanding stops on the CDC circuit. It's the kind of racing that separates the committed from the cautious. Throw on your most aggressive tires, lean into every corner with conviction, and embrace the glorious chaos. As the organizers put it, this soaker is as close to religion as you may ever get.
