What features do you think Zwift is missing in their ride scheduling to make it a more comprehensive and user-friendly experience, and how would you reimagine their current scheduling system to better accommodate the diverse needs of cyclists, from beginners to professional athletes, including those who participate in various disciplines like road cycling, mountain biking, and cyclocross? For instance, would it be beneficial to have a feature that allows users to schedule rides based on specific training goals, such as increasing cadence or improving hill sprints, or perhaps integrate a social aspect that enables users to join group rides and interact with fellow cyclists in real-time? Should Zwift also consider incorporating AI-powered ride scheduling that adapts to a users performance data and goals, providing a more personalized experience? How can Zwifts ride scheduling be improved to cater to the needs of cyclists who participate in virtual events and races?
