Ennis, United States of America · Saturday 11 July 2026
Ennis sits in the heart of Montana's Madison Valley, a region defined by wide-open ranching country, mountain views, and that particular quality of light you get at high elevation. Running here means moving through genuine working landscape rather than a manicured tourist route, with the Madison Range providing a constant dramatic backdrop. The town itself is small and genuine, the kind of place where a marathon still feels like a community event rather than a logistical machine. At over 2600 meters elevation, your body will feel the thinner air regardless of your fitness level, so this is a race that demands respect and smart pacing from the start. The course itself is refreshingly straightforward: flat to gently rolling terrain that won't punish your quads but won't give you much free speed either. You're looking at elevation that ranges across about 300 meters throughout the race, which means there's enough variation to keep things interesting without becoming a mountain slog. The road surface is standard tarmac, and the July timing means you'll be running in genuine warmth at that altitude, which creates its own set of challenges. Early mornings are cool, but exposure in the middle miles will test your heat management. What makes this race worth the trip is the combination of that high-elevation challenge, genuine Montana scenery that doesn't feel manufactured, and the kind of small-town race atmosphere where you actually see the same volunteers multiple times. It's not the fastest marathon course you'll run, but it's the kind of race that rewards preparation and patience. The landscape alone, rolling past ranch land with those mountains framing everything, makes the hard miles feel less like grinding and more like being somewhere that matters.
