As a frequent Zwift user, I need to be able to choose between a flat route and a hilly route so that I can determine which is more appropriate for the ride I want to do that day.
It would be AWESOME if every world had a flat-ish option and a hilly option. For some intervals and workouts, I would like a relatively flat course. I have an extremely difficult time doing my workouts on the New York City Central Park course because it is so hilly. I can’t do 400 W on a 7% downhill. . But I would like to ride that course if I did not have intervals planned.
I highly recommend that each course have a choice and that you let us make it when we first get started.
