Rainbow Ridge 20k and 50k - Rainbow, OR
This event offers two trail distances in Rainbow, Oregon: a 20K and a 50K.

The 20K starts from the upper McKenzie community center and includes a 2,600 foot climb to the Kings Castle summit with views of the McKenzie River valley and Cascade peaks. The return is primarily downhill.
The 50K uses a shuttle to the Olallie North trailhead and begins with about six miles of sustained climbing, including a 3,400 foot gain early in the course. Key summits include Horsepasture Mountain (5,675 ft), Macduff Mountain (5,060 ft), and Kings Castle. The route features long unsupported stretches, technical sections, a steep final descent of about 2,700 feet over the last six miles, and an exposed rocky scramble near the summit before a finish through a covered bridge into the community center.
