What makes a virtual urban ride on Zwift truly immersive and engaging, and are there any routes that stand out for their realistic cityscapes, challenging terrain, and varied scenery, or is it more about the social aspect and the ability to ride with others in a virtual environment that mimics real-world urban cycling experiences? Are there any routes that offer a unique blend of technical challenges, such as tight corners and steep hills, and scenic views, such as virtual city skylines or waterfronts, or are these types of features typically mutually exclusive in virtual urban rides?
