Mastondon Trail Race Tumalo, OR   Mar 1, 2026

The Mastondon Trail Race is composed of 99.7% single track. The races takes place on the BLM trail network called Maston in between Tumalo and Redmond in the shadow of Cline Butte. There are views of the Deschutes river, mountains of Central Oregon, and it’s just a cool trail through the juniper trees and high desert landscape. A relatively flat course with only about 400′ of elevation change, this race is a good early season event to see how the engine is running without too much demand on the early season legs.
