Sunriver, United States of America · Saturday 11 July 2026
Held in Sunriver, Oregon, this marathon takes runners through the heart of central Oregon's high desert landscape. The area sits at an elevation of roughly 1,300 meters above sea level, placing runners in a thinner air environment that demands respect and adaptation. Sunriver itself is a resort community nestled among ponderosa pine forests, offering the kind of quiet, orderly atmosphere that characterizes many planned mountain towns. The setting is genuinely high country, and that elevation will be the most significant factor runners encounter on race day. The Pacific Crest Marathon course is refreshingly straightforward. Runners will find themselves on road surfaces with terrain that stays flat to gently rolling throughout the 42.2 kilometers, meaning there are no punishing climbs or technical descents to navigate. The elevation profile shows only modest undulation across the course, with no significant cumulative gain. This doesn't mean the race will feel easy, though. The high altitude combined with the road surface means runners will feel the effort in their legs and lungs, particularly if they're not accustomed to racing at elevation. The course follows through the area's characteristic pine forest and open high desert terrain, offering a pleasant change of pace from more crowded urban marathons. Pacing strategy becomes important here; runners should plan to start conservatively and let their bodies adjust to the thinner air before attempting to push harder in the final kilometers.
