Run Through Time Marathon

Running through Salida in March means dealing with the quirks of high altitude racing on the eastern slope of the Colorado Rockies. The course sits between 7,070 and 9,020 feet above sea level, which means your lungs will feel the thin air despite the relatively modest elevation gains. The landscape around you is that distinctive Colorado plateau terrain, all sagebrush and piñon pine, with the Sangre de Cristo Mountains as a constant presence to your west. The road surface is solid asphalt throughout, and while the course profile claims gentle rolling terrain, what feels like a false flat at this elevation can become its own kind of grinder. Your legs will feel heavier than expected at mile eighteen, not because of steep hills but because of the cumulative effect of pushing oxygen-thin air. The early spring weather in the Arkansas River valley can be unpredictable, so you might find yourself dealing with wind funneling through the river gorge or sudden temperature swings between sun and shadow. What makes this race feel different from sea-level marathons is how your body responds to the steady altitude pressure rather than dramatic elevation changes. You'll notice the high desert sun working harder on you despite cooler temperatures, and the dry air will hit your throat and lips differently than what you're probably used to. The scenery shifts between the town itself, agricultural land, and open high desert, which can be mentally helpful on the back half when you're searching for anything to focus on besides the remaining miles. The actual flatness to gently rolling character of the terrain means there are no real downhill sections to give your legs a break, so you're grinding steady for the full distance. Most runners find their race pace sits somewhere between five and ten seconds slower per mile than their sea-level equivalent, even with the modest terrain, so adjust your expectations accordingly and focus on effort rather than pace.
