4.5 Mile Trail Run at Silver Falls

Embark on a captivating trail adventure at the 4.5 Mile Trail Run at Silver Falls on March 7, 2026, in Silverton, OR. This revamped event, formerly known as the Buck Mountain Mudslinger, offers a fresh take on trail running with its new course and flexible, multi-loop format. Known for top-notch organization by Run Wild Adventures, this race provides a perfect opportunity for runners to tackle a single 4.5-mile loop or challenge themselves with multiple loops over six hours, with each lap individually timed to support ultra training or a personal best.

The new 4.5-mile loop course navigates a gorgeous stretch of mostly singletrack trail, complemented by a few gravel and paved sections, showcasing a beautiful, quieter side of Silver Falls State Park, away from the famed waterfall trails. While the previous course featured a stout climb, this refreshed route offers approximately 430 feet of total elevation gain and loss, making it a scenic yet accessible trail experience. Typical race day conditions in early March see highs around 53°F and lows around 37°F, with a 27% chance of precipitation, so runners should be prepared for varying Pacific Northwest weather, which can include wet leaves and mud.

Runners will find an aid station conveniently located at the start/finish of each 4.5-mile loop, ensuring consistent support throughout their effort. After crossing the finish line, participants can enjoy the classic Run Wild Adventures post-race spread, complete with refreshments, food, beer, and snacks, all contributing to a relaxed yet energized atmosphere. This event is a fantastic way to experience the diverse beauty of Silver Falls State Park, whether aiming for a quick trail blast or a supported long-distance day in the woods.
