The Pikes Peak Greenway section of the Colorado Front Range Trail is a mile high so keep in mind that each lung full will not count as much. The path parallels the brisk flowing Fountain Creek with a picturesque Rocky Mountain vista nearby to the west. The route beginning at the southern end runs 14 miles to the Air Force Academy. It is hard packed dirt and sand. Trail heads are scarce. I had to jump a low fence next to private property in order to access.
