Conquer the canyon, chase the skyline
Overview
The Yakima Skyline is one of Rainshadow Running’s toughest and most scenic spring races. This iconic trail run traverses the dramatic Yakima River Canyon in Washington’s high desert. With nearly 4,700 feet of elevation gain, relentless climbs, quad-burning descents, and rugged technical trails, this is no ordinary 25K.
Expect sweeping views of the Yakima River, rolling ridgelines lined with wildflowers, and distant glimpses of Tahoma (Mt. Rainier) and Pahto (Mt. Adams); if you can look up between climbs. The course is exposed, often hot and dry, and snakes share the trail, adding an element of true wild. Finishers are rewarded with Rainshadow’s signature finish-line party, plus free on-site primitive camping.
This is more than a race, it’s an adventure.

The route launches at 1,300 ft beside the Yakima River, crosses the suspension bridge, and climbs more than 2,100 ft in two relentless miles to the Skyline Rim Jeep road. Runners dance along rocky ridges carpeted with balsamroot, plunge 1,400 ft to Roza Creek, then grind skyward again for sweeping ridge-running toward the halfway Buffalo Aid Station. Expect exposed single-track, shifting basalt scree, spring wildflowers, and the ever-present canyon wind. Return on the same trail; climb, crest, and ride “the elevator shaft” back to the river for a hero’s welcome.

Dog Policy
Leashed, well-behaved dogs are welcome at the start/finish and on course, but owners must consider hot, rocky terrain and scarce water when deciding to run with their pup.
Note from Kåduka: our staff have done this course multiple times; we don't bring our own pups to the course — there's no water throughout the entire course; it's very dry terrain — but they have a fun time at the Start & Finish.
Charity & Beneficiary
A portion of proceeds supports local trail-maintenance grants through Rainshadow’s “For The Trails” fund, keeping Yakima Canyon’s single-track rugged and runnable.
