The Sky Run 50K: the full desert-to-summit climb
The Sky Run 50K starts at Oliver Lee State Park on the Alamogordo desert floor, around 4,300 feet, and climbs the entire way into the Sacramento Mountains. That is the full sky race experience: you leave the low desert behind and spend the day working uphill into cooler, thinner mountain air, finishing in the high country near Cloudcroft. Respect the early low-elevation miles for the heat they can bring, since the desert floor in October can still run warm even as the finish line sits in cool mountain country.
