Welcome to Stub Stewart State Park, the home base for what aims to be one of the premier 100-mile Ultramarathons in the Pacific Northwest. The race features over 7,000ft of gain, utilizing the Banks Vernonia State Trail (asphalt), the Crown Zellerbach Trail (hard-packed gravel), and dirt trails within the park.
The course is a double out-and-back from the park, starting north on the Banks Vernonia Trail, looping through Vernonia, around Vernonia Lake, and linking up with the Crown Z Trail for approximately twenty miles east towards Scappoose before retracing steps. A second out-and-back on the Banks Vernonia Trail leads to Banks, followed by a return to Stub Stewart Park. The final lap involves the 6.5-mile Stub Stewart Trail Challenge course.
