Billings, United States of America · Sunday 20 September 2026
Running the Montana Marathon in September means experiencing the high desert landscape of south-central Montana on a course that feels deceptively gentle. The elevation starting at just under 1,000 meters will hit you immediately if you've trained at sea level, making those early miles feel heavier than the actual terrain warrants. The course itself is honestly forgiving, with only modest rolling sections rather than any serious climbing, but the landscape conspires to make it feel more exposed than it is. You'll be running across the Billings plateau with big sky above you and the Rimrocks visible in the distance, which sounds romantic until you realize there's minimal shade and September sun in Montana is relentless at midday. The wind can be a factor out here too, sweeping across the open country without anything to break it, so even on a calm day you might encounter sudden gusts that make your effort feel heavier than the grade suggests. By mid-race, your legs will settle into the rhythm of the terrain, but your mind has to contend with the monotony of the high plains. The landscape doesn't change dramatically, which some runners find meditative and others find grinding. You'll pass through residential areas and industrial sections of Billings, then spend stretches on quieter roads where you're mostly alone with your thoughts and the wind. The September weather is actually ideal for running, cool enough that you won't overheat but not so cold that you need extra layers, and by late afternoon you might catch that particular quality of light the high desert gets when the sun gets lower. This is a course for runners who appreciate efficiency and straightforwardness over drama, where the challenge is more about managing the altitude and the elements than fighting the terrain itself.
