I know these are early days and new courses are eagerly awaited.
I would like to see customization of maps.
For instance i ride the Zwift island route, i take it easy most of the time and really hammer the KOM to the best of my ability, i do this every lap, like hill repeats, it gives me something to aim for and encourages me to make the extra effort.
I want to make my own routes with shorter/longer duration between hills and longer/shorter hills depending on what sort of training i am looking for.
This way i could select say 2 minutes hard climbing effort followed by 5 minutes coast and Zwift would generate just such a map to approximate this for me
I realize i could do this myself by timing my own intervals, but hitting the foot of a hill at just the right moment in my interval effort would give the extra encouragement of beating my PB or taking someones KOM.
