This trail starts off of Tyler's Traverse - Downhill in a section where the uphill and downhill segments meet. Duodenum is smooth and has some fun features. Head south down the trail and you'll soon find some nice little banked corners.
At the lollipop junction, stay left to do the loop clockwise. You'll have a gradual climb, then descend down a fun series of banked turns back to the start of the lollipop. Head back up the way you came to return to the junction with Tyler's Traverse - Downhill and Tylers Traverse - Uphill.
