Denver is known as the Mile High City because it is 5,280 feet above sea level. It took us about 6 months to get completely acclimated to the altitude. There are different spots around the city that mark 5,280 feet: Coors Field has a row of purple seats that ring the park marking the exact location of 5,280 feet and there is a step at the State Capitol building in Denver that is exactly 5,280 feet. At the Pepsi Center they warn the audience that at 5,280 feet oxygen levels are at 60% because Denver is 1 mile above sea level. We have been told that we are building stronger lungs so when we go back to sea level we will be superstars!
