Crown Stub 100

Welcome to Stub Stewart State Park….. it is such a gem of the Oregon State Park system! 

We are grateful to be able to utilize this amazing outdoor adventure hub as our home base for what we hope becomes one of the Premier 100 mile Ultramarathons in the Pacific Northwest!

The race has over 10,000ft of gain as it traverses a combination of the Banks Vernonia State Trail (primarily asphalt) the Crown Zellerbach Trail (primarily hard packed gravel) and roughly 10% of the course will be run on the dirt trails of the park itself. The course consists of a double out and back from the park…starting in a northerly direction on the Banks Vernonia Trail. As you come into the City of Vernonia you will be directed around Vernonia Lake, eventually linking up with The Crown Z Trail. The Crown Z Trail will take you on a ride in an easterly direction for roughly twenty miles, turning you around just before entering the City of Scappoose (Native American for “Gravelly Plain”) Ancesteral tribal lands of The Chinook. 

Here you will turn around and retrace your steps back on the Crown Z & Banks Vernonia Trail (BVT). As you are making your way back, please encourage your fellow competitors & adventurers. Whether you are a seasoned vet of ultrarunning or this is your first step into the cave…. Ultrarunning is rooted in community, uplifting each other through kindness & encouragement. We please ask that you keep this tradition alive as a Bivouac Racing Participant.

When you reach the Stub Stewart Park crossing on the Banks Vernonia Trail (Stubby AS mile 72) you will continue in a southernly direction on the BVT for 10 miles, turning around in Banks. Retracing your steps back to the (Stubby AS mile 92). Here you will continue on the BVT for almost a mile before making a hard right turn on the Boomscooter Trail. From here you will follow the trail markings back to the Hill Top Day Use area. (mile 93.5) 

You will see the finish line in all its glory…..but, you have One more lap. You will follow the 6.5 mile Stub Stewart Trail Challenge course for one time around. Upon completion you be able to embrace that Finish!

Congratulations….You are a Hundred Mile Finisher & you have the Buckle to prove it!
