Pikes Peak (originally Pike's Peak, see below) is a mountain in the Front Range of the Rocky Mountains, 10 miles (16 km) west of Colorado Springs, Colorado, in El Paso County. It was renamed from "El Capitan" which the Spanish settlers had referred to it for decades to Pike's Peak after Zebulon Pike, an explorer who led an expedition to the southern Colorado area in 1806. At 14,115 feet (4,302 m), it is one of Colorado's 54 fourteeners. Drivers race up the mountain in a famous annual race called the Pikes Peak International Hill Climb. The peak is also the site of the annual Pikes Peak Marathon and Ascent foot races on Barr Trail. The upper portion of Pikes Peak is a federally designated National Historic Landmark.
