The Swiftwater to Steamboat North Umpqua Tr1414 ride combines the Tioga and Mott sections into an easy riverside ride, with enough short climbs to keep it challenging and interesting for reasonably fit beginner to intermediate riders.
Although it is a fast ride, the full OAB length will be too much for some riders.
Use of a shuttle from Steamboat to Swiftwater would greatly reduce the aerobic challenge, possibly including the Panther section, starting from the FR4714 Apple Creek campground.
The 1mi Bob Butte section offers the toughest climbing, with an 850' ascent at a 16% grade, too much for beginners and many intermediates, but it is a short enough hike to be manageable.
Cougar Creek Tr1507 and McDonald Tr1515 trails are too steep for an OAB ride, but a shuttle is possible, when the local fireroads are passable.
Be sure to keep a full tank of gas, and get other provisions before the ride, as the Steamboat shops are not 24/7.
Expect some trailside poison oak and prepare as needed. Try using Tecnu before the ride.
The Mott section of North Umpqua Tr1414 and Riverview Tr1530 can be used to create an 'Easy' 14mi (2300' ascent) CCW loop, which involves less elevation change than riding the Tioga section.
The ride can be extended by including the Panther section, as an OAB to the FR4714 Apple Creek campground.
