Challenge Unlimited offers cycling and biking adventures in Colorado and in many parts of the most beautiful places in the world. This year we are celebrating our 24thanniversary guiding bike tours out of Colorado Springs. We are the oldest and most experienced bike touring company in Colorado and we have created the most exciting tourist attraction in the west.
We offer bike tours down Pikes Peak - America's Mountain, through Gold Camp in Colorado Springs and an Aspen tour in the fall. Add a Cog Railway ride, rock climbing and zip-lining to your Pikes Peak bike tour.
