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.
