Tough Mudder Classic Seattle is one for the record books because we’re coming back to the legendary Palmer Coking Coal Company for a 6th year in a row. Just 40 minutes from downtown Seattle, this course features steep-sided gravel pits, deep-wood runs, a century-old coal heap, and one-of-a-kind black coal mud. So crew up and get ready for a challenge bigger and bolder than anything you’ve seen this side of Mt. Rainier.
