Is it truly effective to utilize Zwifts route-specific challenges as a primary tool for goal setting, or is this approach merely a simplistic solution that neglects the complexities of individual rider needs and progress tracking? Do the pre-defined challenges offered by Zwift, such as the Alpe du Zwift or the Innsbruckring, provide sufficient structure and motivation for riders to set realistic and achievable goals, or do they instead create unrealistic expectations and foster a culture of competition over personal growth? Furthermore, how do the route-specific challenges account for the nuances of off-road or mixed-surface riding, and can they be adapted to accommodate riders who regularly incorporate unpaved or trail segments into their training?
