The Stub Stewart Trail Challenge is the 3rd race (out of 4) in Bivouac Racing’s Oregon State Park’s Trail Series. This event includes a 1/2 marathon and a 1/4 marathon distance with a mix of paved and unpaved trail. The paved portion will be run on the Banks-Vernonia Trail. If you like variety on your runs, this is the race for you. From mixed running surfaces to gently rolling hills to tough climbs, this race promises a bit of everything. As you can see from the elevation map below, there is a reason the word “challenge” is in the race name!

Both courses are loop courses, with the 1/2 marathon running the loop twice. Once clockwise and then counter clockwise on the 2nd lap. There will be 2 aid stations on the course, but be prepared – Bivouac Racing events are cupless, so BYODV (bring your own drinking vessel!)
After the race there will be food and beer, as well as a Bivouac Racing mug for all finishers. There will also be a chance to win some cool SWAG, so stick around afterwards!
As this race is in a state park, there is a $5 per vehicle Day-Use Fee that will be required for all vehicles entering the park. So, be sure to have an extra $5 on hand.
