The Mastondon 10ish Miler 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, the mountains of Central Oregon, and a cool trail through some juniper trees. A relatively flat course with only about 400′ of change, this race is a good early season race to see how the engine’s running without too much demand on the early season legs. This run is composed of 99.7% single track. With a mere 400′ of elevation gain you can really let them fly on this roughly 10 mile course. With great views of the mountains, river, and juniper forest this one will surely be a good time. The Maston trail system is a great winter time training ground here in Central Oregon and I think this course will be a great addition to the already great trail running we enjoy.
