About Alpine Running
Alpine Running is a trail race organization rooted in the spirit of the Cascade Mountains, offering a collection of rugged, scenic, and soul-filling events across Oregon and Washington. Founded in 2017 by longtime mountain runner and nurse Trevor Hostetler, Alpine Running was born from a deep passion for wild places and the transformative power of endurance running. Since then, it has grown into a close-knit community of runners who value adventure, camaraderie, and purposeful connection to the trails.
At its core, Alpine Running embodies a low-key yet high-quality ethos. Events are marked by personal touches, from meticulously flagged courses to thoughtful safety planning and warm, volunteer-powered aid stations. Whether you’re pushing your limits in a mountain ultra or enjoying the views on a shorter course, every Alpine race is designed to challenge and uplift.
From the Elkhorn Crest 50 to other remote alpine races, Alpine Running events are as much about self-discovery as they are about competition. If you're seeking meaningful mountain miles with an authentic trail family, Alpine Running will welcome you with open arms and wild terrain.
