Oregon’s Ugliest Sweater Run, brought to you by The Dirty U

On Saturday, December 12, 2026, runners will gather at Alton Baker Park in Eugene, Oregon for an exhilarating race that promises to showcase the natural beauty and vibrant running community of this Pacific Northwest city. Nestled along the Willamette River, the park offers a picturesque backdrop with its lush greenery and serene water views.
The course weaves through well-maintained trails that wind around the riverfront, providing runners with stunning vistas at every turn. The terrain is primarily flat but includes gentle inclines that challenge participants without being overly taxing. As you run along the banks of the Willamette River, expect to see a variety of wildlife and enjoy the crisp winter air.
Eugene's running culture will be on full display as local runners join athletes from around the world for this event. The race is designed not just as a competition but also as an opportunity to explore one of Oregon’s most beloved parks during its dormant season when trees are bare, making way for clearer views and crisp air.
Post-race festivities include awards ceremonies for various categories and refreshments at the finish line area where runners can socialize with fellow participants. The event is perfect for both competitive athletes looking for a challenging course and casual runners who want to enjoy a scenic run in one of America’s premier running cities.
Registration opens soon, so mark your calendars and prepare to experience the unique blend of natural beauty and community spirit that makes this race an annual highlight for many runners.
