Dark Divide 100M

100MFriday, September 4, 2026Washington

A hundred miles of raw wilderness challenge

Overview

The Dark Divide 100 Mile Endurance Run isn’t just another ultramarathon. It’s a test of grit, wilderness skill, and unshakable willpower. With steep ascents, rocky technical singletrack, and vast stretches of remote terrain, this race asks everything of you—and then some.

Runners will climb and descend over 26,000ft as they navigate wild ridgelines, deep forests, and long miles between aid stations. The Dark Divide is not for beginners—it’s a brutal, beautiful, bucket-list challenge that will push you to your edge and reward you with jaw-dropping views, camaraderie, and the thrill of finishing one of the hardest 100 milers out there.

The Dark Divide course is a rugged journey through some of Washington’s most dramatic backcountry. Expect endless climbs, big descents, exposed ridgelines, and over 75% technical singletrack. You’ll travel through the Roadless Area where aid stations are up to 16 miles apart and where course markings are minimal to preserve the wilderness feel. This is a course where navigation matters, your legs will scream, and your heart will soar.

  • Stunning views of the Dark Divide Wilderness

  • Remote alpine ridges with vast horizons

  • Long, steep climbs that test every ounce of endurance

  • Minimal course markings for true backcountry racing

About Wonderland Running

Wonderland Running

Wonderland Running is a quirky, community-first trail race organization based in the Pacific Northwest, bringing creativity, inclusivity, and adventure to every event. Officially founded in 2019, but with roots in DIY group runs long before that, Wonderland Running was born out of founder Sean Harrasser’s deep love for wild places and his solo, unsupported circumnavigation of the Wonderland Trail around Mount Rainier. Since then, the organization has evolved into a passionate crew of runners, mischief-makers, and outdoor enthusiasts who are dedicated to crafting memorable race experiences in truly magical settings.

The Wonderland Running team is made up of ultrarunners, artists, race directors, educators, tech wizards, and outdoor lovers who embrace the spirit of trail running in all its unpredictable, joyful, and humbling glory. With job titles like Executive Bad Hill Idea Conspirator and Master Hill Technologist, their ethos is as much about fun and self-expression as it is about fitness and finish lines.

Based in Oregon, with team members spread across Redmond, Bend, Portland, and Hillsboro, Wonderland Running is at the heart of the PNW trail scene. Whether you’re a seasoned ultrarunner or showing up to your first trail race, you’ll find a warm welcome, a clever hill pun, and an unforgettable experience waiting at the start line.

For those looking to connect with trail running beyond the stopwatch, Wonderland Running offers something rare: a race company that balances soulful exploration, creative expression, and genuine community.
